Gorgonians are one of the most dramatic and rewarding corals you can add to a reef tank. They sway in the current like living curtains, create natural structure that fish and seahorses love, and add a dimension of color and movement that few other corals can match.
They also have a reputation for being difficult — and that reputation is only half-deserved.
The honest answer is this: Caribbean photosynthetic gorgonians are genuinely beginner-friendly. Non-photosynthetic gorgonians are recommended for experts or advanced aquarists . The word "gorgonian" covers both, which is why the internet is full of conflicting advice. This guide is going to help you understand exactly which type is which, what each one needs, and how to set yourself up for success before you buy.
At Foxy Saltwater Tropicals, we collect our gorgonians directly from the Florida Keys and Caribbean waters. About 90% of our Caribbean marine life is hand-collected by our own team. That hands-on knowledge is the foundation of everything we know about how these corals behave before, during, and after collection — and it's what we're going to share with you here.
What Is a Gorgonian Coral?
Gorgonians (Order Alcyonacea, formerly Gorgonacea) are octocorals — soft corals with eight-petaled polyps arranged on branching, fan-like, or whip-like structures. They belong to the same subclass as soft corals and sea anemones but are distinct from both. Their skeletons are made from either flexible gorgonin protein or rigid calcareous spicules, depending on species. This is what gives them their characteristic swaying movement: flexibility is built into their biology.
There are over 1,200 known gorgonian species worldwide, found across tropical and subtropical oceans at depths ranging from just below the surface to thousands of feet deep. Common names you'll see in the aquarium trade include sea fans, sea rods, sea whips, sea plumes, and sea fingers — all gorgonians, just different growth forms.
What Makes Gorgonians Different from Other Soft Corals
Most soft corals are encrusting, mounding, or blob-shaped. Gorgonians build branching structures that stand tall in the water column, creating habitat — natural hitching posts for seahorses, shelter for gobies and cardinalfish, and food-catching surfaces that filter planktonic particles from the current. When their polyps are fully extended, a healthy gorgonian looks like it's covered in soft fuzz. When they retract, the branches look smooth and wiry.
That structural quality is exactly what makes them so visually rewarding in a reef tank — and what makes choosing the right species so important. Get the right type for your setup and experience level, and gorgonians are some of the most forgiving corals in the hobby. Get the wrong type, and they become one of the most frustrating.

Photosynthetic vs Non-Photosynthetic Gorgonians — The Most Important Decision You'll Make
Before you buy any gorgonian, you need to understand this single distinction. It will determine your lighting setup, your feeding schedule, your temperature target, and your likelihood of long-term success.
What Is a Photosynthetic Gorgonian?
Photosynthetic gorgonians (also called zooxanthellate or PS gorgonians) contain symbiotic zooxanthellae algae in their tissue. These algae photosynthesize and provide the coral with much of the energy it needs to survive. That means the coral gets most of its nutrition from light — just like your LPS and SPS corals.
This makes them significantly easier to keep. You provide moderate to high lighting and good water flow, supplement with food once or twice a week, and these corals will grow steadily in a well-run reef system. Most Caribbean photosynthetic gorgonians are shallow-water species, adapted to the bright, wave-swept conditions of Florida and Caribbean reefs. In a tank, that translates to: bright light, strong alternating flow, stable parameters. That's a standard reef setup.
Care level: Beginner to intermediate.
What Is a Non-Photosynthetic Gorgonian?
Non-photosynthetic gorgonians (NPS, or azooxanthellate gorgonians) contain no symbiotic algae. They derive 100% of their nutrition from filter feeding. In the wild, they live in deeper, darker water where nutrient-laden currents bring a constant supply of plankton and fine organic particles. In an aquarium, you have to replicate that food supply — every single day.
Without daily feeding, NPS gorgonians starve and undergo tissue recession within days to weeks. They also require lower temperatures than photosynthetic types (because they come from deeper, colder water), and they must be placed away from intense lighting, which encourages the algae growth that can smother their branches. This is not a coral you can neglect or feed "when you think about it."
Care level: Advanced to expert. Not recommended for beginners or casually managed tanks.
How to Tell If a Gorgonian Is Photosynthetic Before You Buy
This is one of the most frequently asked questions in the hobby — and the answer is surprisingly practical.
Look at the polyp color.
- Brown or tan polyps almost always indicate a photosynthetic species. The brown color comes from the zooxanthellae living in the polyp tissue.
- Bright white, orange, red, yellow, blue, or pink polyps typically indicate a non-photosynthetic species. NPS gorgonians invest in vivid colors precisely because they don't need to protect or house algae.
Look at the branch color as a secondary signal. Muted purples, tans, golds, and greens tend to be photosynthetic. Vivid reds, oranges, and electric yellows are usually NPS. This isn't a perfect rule — always confirm with your seller — but it works the vast majority of the time.
Ask before you buy. A good retailer knows whether their stock is photosynthetic or non-photosynthetic. We always label our gorgonians accordingly on each product page.
Are Caribbean Gorgonians Easier Than Pacific Gorgonians?
Yes — significantly, and this is worth understanding before you shop.
Most Caribbean gorgonians available in the aquarium trade are photosynthetic. They evolved in shallow, bright, warm, wave-swept environments and are adapted to the exact conditions most home reef tanks provide. Generations of reef keepers have successfully kept Caribbean sea rods, sea fans, and sea whips in standard reef setups.
Most of the flashy, colorful NPS gorgonians you'll see in photos online — vivid oranges, brilliant reds, electric yellows — are Pacific or deep-water species. They are stunning. They are also genuinely difficult, require dedicated systems, and have a high failure rate outside of expert hands.
For reef keepers who want gorgonians with reasonable success rates, Caribbean species are the right choice. Everything Foxy carries is Caribbean-sourced from the Florida Keys. That means our photosynthetic species have an immediate advantage before they even arrive at your door.
Foxy's Caribbean Gorgonian Species Guide
Every gorgonian we sell comes from the waters of the Florida Keys and surrounding Caribbean region — hand-collected by our team. Here's what you're working with, species by species.
Photosynthetic Caribbean Gorgonians (Beginner to Intermediate)
These species are suitable for reef keepers with a running, stable saltwater system. They do not require daily feeding and will thrive under standard reef lighting.
Corky Sea Finger (Briareum asbestinum)
Also called Deadman Fingers, Corky Sea Fingers are the most beginner-friendly gorgonian we carry — and possibly the most forgiving soft coral you can put in a reef tank. We collect them from shallow Caribbean waters and the Bahamas, where they grow in columns up to 24 inches tall in ample sunlight and strong tidal flow.
In an aquarium, they need medium to strong water flow and fluorescent or reef-capable LED lighting. They are photosynthetic and require less light than hard corals but still need adequate intensity to thrive. One unique thing about this species: they generate a mucus coating that sheds every 10 days or so. This is completely normal — it's how the coral rids itself of surface debris. First-time gorgonian keepers sometimes panic when they see this; don't. Leave it alone and it will slough off on its own.
Give Corky Sea Fingers space. They spread fast and will grow over neighboring soft corals if placed too close. Feed tiny live plankton occasionally and dose trace elements including iodine, strontium, and calcium for healthy growth.
- Lighting: Moderate
- Flow: Medium to strong
- Temperature: 72–82°F
- Feeding: Not required; occasional phytoplankton beneficial
- Best for: Beginners; Caribbean biotope tanks; seahorse systems
Purple Frilly Gorgonian (Pseudopterogorgia species)
Also called Purple Plume, the Purple Frilly grows in an irregular, horizontal branching pattern with a feathery, plume-like appearance that looks remarkable when flow moves through it. We collect these from offshore reefs in the Florida Keys.
This species is photosynthetic and requires moderate to high lighting, moderate to high water flow, and weekly supplemental feeding (brine shrimp, marine snow, zooplankton, or flaked coral food). It is semi-aggressive — give it buffer space from neighboring corals. Temperature range is 74–82°F.
Cyanobacteria is the main enemy of this species. If flow drops, algae and cyano will settle on the branches and deteriorate the coral quickly. Strong, consistent, alternating flow is non-negotiable.
- Lighting: Moderate to high
- Flow: Moderate to high
- Temperature: 74–82°F
- Feeding: Weekly supplemental recommended
- Best for: Intermediate reef keepers; tanks with strong flow
Purple Whip Gorgonian
A beautiful, vivid purple species with a single whip-like branching structure. We source Purple Whip Gorgonians from off the coast of the Florida Keys. This is a photosynthetic species that requires strong intermittent water flow — this is perhaps its single most important care requirement. Insufficient flow leads directly to algae and cyanobacteria problems that can deteriorate the coral rapidly.
Provide moderate to high lighting. Supplement weekly with zooplankton and filter-feeding foods (frozen brine shrimp, marine snow). Anchor to live rock or substrate with epoxy; do not place it too close to other corals.
- Lighting: Moderate to high
- Flow: Strong, intermittent
- Temperature: 72–82°F
- Feeding: Weekly supplemental recommended
- Best for: Tanks with established wavemakers or programmable flow
Purple Rod Gorgonian
Collected from the waters just off the Florida Keys, the Purple Rod is a photosynthetic gorgonian that grows to about 12 inches in height. It requires moderate skill to maintain, is considered semi-aggressive, and can sting neighboring corals that get too close. Give it space.
High water flow is essential — without it, cyanobacteria and red band or black band infections can develop and cause rapid deterioration. If cyano does appear, a careful freshwater dip of the same temperature can kill the bacteria. Trimming infected branches early can help save the rest of the colony.
Moderate to high lighting is required. Weekly supplemental feeding with marine snow, zooplankton, or banded shrimp is recommended even though it is photosynthetic. It can be fragged and has been known to reproduce in captivity.
- Lighting: Moderate to high
- Flow: High
- Temperature: 72–82°F
- Feeding: Weekly supplemental recommended
- Best for: Intermediate reef keepers with strong flow systems
Purple Bush Gorgonian
Very similar in care requirements to the Purple Rod, the Purple Bush grows to approximately 12 inches and is photosynthetic. Also collected from the Florida Keys. It is semi-aggressive and needs sufficient spacing from neighboring corals.
High water flow is the top priority. Moderate to high lighting is required. Weekly supplements of marine snow, zooplankton, or banded shrimp are recommended. Like other purple gorgonians, cyanobacteria is the most common problem — and the solution is always flow first. If cyano develops despite good flow, remove the coral and perform a brief freshwater dip of the same temperature to kill the bacteria. Trimming and allowing healthy sections to regrow is also effective.
- Lighting: Moderate to high
- Flow: High
- Temperature: 72–82°F
- Feeding: Weekly supplemental recommended
- Best for: Intermediate reef keepers
Tan Rod / Rusty Rod Gorgonian (Golden Sea Rod)
A hardy, tree-like photosynthetic gorgonian collected from the Florida Keys. Branches range in color from tan to golden yellow to rusty brown with white-tipped polyps, which is where all the name variations come from. This species is one of the more forgiving photosynthetic gorgonians and is an excellent choice for relatively new reef keepers who want the gorgonian look without extreme demands.
Moderate lighting and medium to strong water flow. Feed several times per week with plankton or invertebrate food for optimal health. Dose trace elements: iodine, strontium, and calcium. This species can be pruned and propagated, and fragments can be re-anchored to rubble or live rock.
- Lighting: Moderate
- Flow: Medium to strong
- Temperature: 72–78°F
- Feeding: Several times per week recommended
- Best for: Beginners to intermediate; excellent first gorgonian
Green/Yellow Whip Gorgonian (Yellow Sea Whip)
Sourced directly from the Florida Keys, the Green/Yellow Whip is a very hardy photosynthetic gorgonian with a whip or tree-like structure. These tend toward a yellowish-green color and have a slightly fuzzy appearance when polyps are extended. Being photosynthetic means minimal feeding and minimal supplementation requirements. This is an excellent beginner species.
One fun note from the field: seahorses love these. Yellow Sea Whips make perfect hitching posts and are specifically recommended for seahorse systems. If you're building a seahorse tank, this is one of the best corals to include for natural enrichment.
- Lighting: Moderate to high
- Flow: Medium to strong
- Temperature: 72–82°F
- Feeding: Minimal; occasional phytoplankton beneficial
- Best for: Beginners; seahorse aquariums; Caribbean biotope tanks
Regal Sea Fan (Leptogorgia hebes)
A photosynthetic gorgonian with a classic fan-like branching structure. Moderate lighting and medium to strong indirect flow. While photosynthetic, it benefits from supplemental feeding 1–3 times per week — phytoplankton, fine zooplankton, liquid coral foods, or marine snow. Supplement with calcium (380–450 ppm), alkalinity (8–10 dKH), and magnesium (1,250–1,350 ppm). Temperature: 72–78°F.
- Lighting: Moderate
- Flow: Medium to strong, indirect
- Temperature: 72–78°F
- Feeding: 1–3 times per week supplemental
Non-Photosynthetic Caribbean Gorgonians (Advanced Care Required)
These species are not recommended for beginners or for tanks that are not yet stable and mature. They require daily feeding and lower temperatures than photosynthetic species — and without both, they will not survive long-term.
Red Finger Gorgonian (Diodogorgia nodulifera)
We source Red Finger Gorgonians from the deep waters off the Florida Keys — typically from 60 to 100 feet depth. That depth tells you everything you need to know about their care requirements. These are not shallow-water, bright-light corals. They are deep-water filter feeders that receive little to no direct sunlight in the wild and exist in cooler, darker, nutrient-rich water column environments.
In an aquarium, Red Finger Gorgonians require low lighting (best viewed at night, when their white frilly polyps are fully extended), medium to strong flow to deliver food and prevent algae, and cooler temperatures: 68–75°F. A chiller may be required depending on your ambient room temperature and tank equipment.
Feeding is mandatory and must happen daily. Red Finger Gorgonians are carnivores. Feed baby brine shrimp, frozen thawed foods, PhytoPlan, and filter-feeding invertebrate foods. A planktonic drip system is strongly recommended for dedicated NPS setups. Turn off pumps for 20–30 minutes during feeding so food reaches the polyps before it's swept away.
Micro algae and cyanobacteria are constant threats — low lighting and proper flow are your defenses. Dose trace elements: iodine, strontium, and calcium. Branches are brittle and break easily, which naturally aids propagation.
This is not a coral for beginners. It is, however, one of the most visually stunning animals in the Caribbean reef ecosystem — and deeply rewarding for experienced keepers.
- Lighting: Low
- Flow: Medium to strong
- Temperature: 68–75°F (chiller often required)
- Feeding: Daily, mandatory — carnivore
- Best for: Advanced/expert reef keepers; dedicated NPS systems
Yellow Finger Gorgonian (Diodogorgia nodulifera)
Found in deep water close to 100 feet in the Florida Keys, the Yellow Finger Gorgonian is the same species as the Red Finger with a different color morph. Its branches display brilliant frilly white polyps that are best viewed at night in low light conditions.
Care requirements are identical to the Red Finger: low lighting, medium to strong flow, temperatures of 68–75°F (chiller likely needed), and daily carnivore feeding — baby brine shrimp, frozen thawed foods, PhytoPlan, filter-feeding invertebrate foods, with a planktonic drip strongly recommended. Supplement with iodine, strontium, and calcium.
One fun note from our product page: seahorses use Yellow Finger Gorgonians as hitching posts. While this species is high maintenance for the aquarist, it serves a beautiful dual purpose in species-appropriate systems.
- Lighting: Low
- Flow: Medium to strong
- Temperature: 68–75°F (chiller often required)
- Feeding: Daily, mandatory — carnivore
- Best for: Advanced/expert reef keepers
Colorful Sea Whip (Leptogorgia virgulata)
A non-photosynthetic gorgonian species available at Foxy. It does not rely on photosynthesis, which means intense lighting is unnecessary and can encourage nuisance algae growth on the branches. Low to moderate lighting is recommended.
Consistent medium to strong, indirect water flow is essential — it delivers food and prevents detritus and algae from accumulating. Feed 3–7 times per week with phytoplankton, fine zooplankton, rotifers, copepods, liquid coral foods, or marine snow-type products. Target feeding with a turkey baster or pipette is beneficial. Temperature: 72–78°F. Stable chemistry: calcium 380–450 ppm, alkalinity 8–10 dKH, magnesium 1,250–1,350 ppm.
- Lighting: Low to moderate
- Flow: Medium to strong, indirect
- Temperature: 72–78°F
- Feeding: 3–7 times per week — non-photosynthetic
- Best for: Intermediate to advanced keepers
Water Parameters for Gorgonian Coral
| Parameter | Photosynthetic (PS) | Non-Photosynthetic (NPS) |
|---|---|---|
| Temperature | 72–82°F (22–28°C) | 68–75°F (20–24°C) — chiller may be needed |
| Salinity | 1.024–1.026 | 1.024–1.026 |
| pH | 8.1–8.4 | 8.1–8.4 |
| Alkalinity | 8–12 dKH | 8–10 dKH |
| Calcium | 380–450 ppm | 380–450 ppm |
| Magnesium | 1,250–1,350 ppm | 1,250–1,350 ppm |
| Nitrates | Low (0–10 ppm) | 5–10 ppm acceptable |
| Phosphates | Low | Low to moderate |
The temperature difference between photosynthetic and NPS gorgonians is one of the most commonly overlooked requirements and one of the easiest ways to lose a deep-water gorgonian. Red Finger and Yellow Finger Gorgonians collected from 60–100 feet of depth have never experienced the warm temperatures of a standard reef tank (76–80°F) in the wild. Keeping them at 68–75°F is not optional.
Supplement all gorgonians with trace elements including iodine, strontium, and calcium. These are important for structural growth and overall tissue health.
Lighting Requirements for Gorgonian Coral
Photosynthetic gorgonians need moderate to high lighting. They are shallow Caribbean water animals that evolved under intense tropical sunlight. Full-spectrum LED setups with both blue and white channels work well. Position photosynthetic gorgonians in the middle to upper portion of your rockwork, where light intensity is highest.
Acclimate new photosynthetic gorgonians to your lighting gradually — start with a lower intensity or a shaded position for the first one to two weeks before moving them to full lighting. Sudden exposure to intense light after the dimmer conditions of shipping can stress the tissue.
Non-photosynthetic gorgonians require dim to no light. Direct intense light encourages algae overgrowth on their branches — one of the primary causes of NPS gorgonian failure. For strict NPS species like Red Finger and Yellow Finger, limiting the light cycle to less than six hours per day is often recommended. Position NPS gorgonians under overhangs, in shaded rockwork, or in lower regions of the tank. The best time to observe them — and feed them — is at night when their polyps are fully extended.
The practical rule: brown polyps = more light; bright/white/red/orange polyps = less light.
Flow Requirements for Gorgonian Coral
Strong, consistent water flow is non-negotiable for all gorgonians, regardless of type. This is the single most important factor in long-term gorgonian health — more important than feeding, more important than lighting (for photosynthetic types), and the number one preventable cause of death.
Flow serves three purposes in a gorgonian tank:
- Prevents algae and cyanobacteria. Without flow, algae settles on the branches and begins to smother tissue. Cyanobacteria — the reddish-brown slime that appears on low-flow surfaces — can cause a gorgonian to deteriorate within days once established.
- Delivers food. Every gorgonian is a filter feeder to some degree. Flow carries planktonic particles to the polyps.
- Replicates natural wave surge. In the wild, Caribbean gorgonians live in the wave-swept shallows where current constantly changes direction. Alternating or intermittent flow (not a steady laminar blast) is ideal.
Use wavemakers or programmable pumps that create a back-and-forth surge pattern. Position gorgonians so that flow reaches them from the side or front, causing them to sway gently. Turbulent, chaotic flow is fine — what you want to avoid is dead spots and low-flow pockets.

Feeding Your Gorgonian Coral
Photosynthetic Gorgonian Feeding
Photosynthetic gorgonians do not require feeding to survive. Zooxanthellae provide the primary nutrition through photosynthesis. However, supplemental feeding 1–2 times per week meaningfully improves coloration, growth rate, and polyp extension. It becomes more important in tanks with very low nutrient levels (ultra-low nitrate/phosphate SPS systems).
Best supplemental foods for photosynthetic gorgonians:
- Marine snow or reef snow products
- Zooplankton (rotifers, copepods)
- Phytoplankton
- Fine coral foods
- Baby brine shrimp
Use a turkey baster or pipette to target feed. Reduce pump flow for 20–30 minutes after dosing to allow the coral to capture food before it's diluted into the water column.
Non-Photosynthetic Gorgonian Feeding
NPS gorgonians must be fed daily — this is not optional and cannot be rounded down to "a few times per week." Without daily feeding, tissue recession will begin. Without a consistent feeding routine, NPS gorgonians will slowly starve even if everything else in the tank looks good.
Best foods for NPS gorgonians:
- Baby brine shrimp (nauplii)
- Phytoplankton (fine particle)
- Rotifers
- Copepods
- Reef snow / marine snow
- Fine frozen thawed foods
- Filter-feeding invertebrate foods (PhytoPlan and similar)
Feed at night when polyps are fully extended — this is when NPS gorgonians are actively capturing food and will get the most benefit from target feeding. Turn off pumps for 20–30 minutes. For heavily stocked NPS tanks, consider setting up a planktonic drip that continuously introduces fine food particles into the water column. This more closely replicates the constant nutrient flow these corals experience in the wild.
We carry Phyto-Feast Live in our store — a blend of six marine microalgae widely used for filter-feeding corals, invertebrates, and gorgonians. It works well as a supplemental food for both photosynthetic and NPS species.
Placement and Anchoring in Your Reef Tank
Where to Place Gorgonians
- Photosynthetic species: Middle to upper rockwork, in the path of flow, under your primary lighting. Give them room to sway without touching neighboring corals.
- NPS species: Lower in the tank, under overhangs, in shaded areas. Still need good flow — position them to receive current without direct intense light exposure.
All gorgonians need buffer space from neighboring corals. Some gorgonian species release allelopathic chemicals that can stress nearby cnidarians. Encrusting types like Corky Sea Fingers can overgrow adjacent corals if they're placed too close and have room to spread. A safe general rule is to keep a hand's width of clear space between gorgonians and their nearest neighbors when you first place them — and monitor over the following weeks as the coral establishes.
How to Anchor a Gorgonian
Apply reef-safe super glue gel or two-part epoxy to the base of the gorgonian and press it firmly against live rock or rubble. Hold it in place for 20–40 seconds until the adhesive sets. You may need to keep your hand in the tank for the full duration — this is normal and worth doing right.
Once anchored, the coral's tissue will gradually grow over and bond to the substrate on its own. This natural overgrowth creates a stronger bond than the adhesive alone. Expect the coral to look slightly stressed for the first few days as it adjusts to placement — this is normal.
You can also place gorgonians directly into the substrate if the base is wide enough to support them. Propping them against rockwork until the epoxy cures is a common technique for awkwardly shaped pieces.
Compatible Tankmates for Gorgonian Coral
Gorgonians are peaceful to semi-aggressive (depending on species) and generally safe in community reef tanks with the right neighbors.
Safe tankmates:
- Small reef fish: gobies, blennies, firefish, cardinalfish, dottybacks
- Shrimp species (banded coral shrimp, cleaner shrimp, peppermint shrimp)
- Hermit crabs and snails (cleanup crew)
- Other peaceful soft corals with adequate spacing
Use caution with:
- Dwarf angelfish — some individuals nip at gorgonian tissue
- Butterflyfish — some species target soft coral polyps
- Large aggressive fish that may knock or damage delicate branches
Special note — Seahorses:
Caribbean gorgonians are among the best natural hitching posts available for seahorse tanks. Both photosynthetic and NPS species work, but the photosynthetic varieties (Green/Yellow Whip, Tan Rod, Corky Sea Finger) are the most practical choice for a seahorse system since they don't require the daily feeding and temperature management that NPS species demand. If you're setting up a seahorse aquarium, gorgonians are a genuinely beneficial addition — both for the seahorse and for the tank's natural aesthetic.
See our [Seahorse Habitat Compatibility guide] for more detail on building a seahorse-appropriate reef environment.
Common Gorgonian Problems and How to Fix Them
Problem 1: Algae or Cyanobacteria on the Branches
This is the most common gorgonian problem, and the cause is almost always the same: insufficient water flow.
What it looks like: Green or brown algae coating branches; reddish-brown slime (cyanobacteria) forming on branch surfaces.
What to do:
- Increase flow first. Reposition the coral or add flow. This is the fix in the majority of cases.
- If cyanobacteria has established, remove the gorgonian from the tank and perform a brief freshwater dip (same temperature as your tank water) — this kills the bacteria on contact. Do not expose the coral to air. Keep the dip under two minutes.
- If algae has attached to branches, you can use a very soft brush to gently dislodge it while the coral is underwater — never scrub aggressively.
- Trim heavily affected branches to prevent spread and allow healthy sections to regrow.
Prevent it: Strong alternating flow, low to moderate nutrients, and proper lighting (not too bright for NPS types) are your long-term defenses.
Problem 2: Polyps Closed or Not Extending
What it looks like: Branches look smooth and bare. No fuzz. No movement.
What it means: The coral is stressed, adjusting, or unhappy with one or more parameters.
Common causes and fixes:
- New arrival: Newly introduced gorgonians often keep polyps closed for 5–14 days while acclimating to your tank's water chemistry, flow, and lighting. This is normal. Maintain stable parameters and give it time.
- Poor water quality: Test ammonia, nitrite, nitrate, pH. Even small parameter spikes can cause polyp retraction.
- Incorrect flow: Both too much direct turbulent flow and too little flow can cause retraction. Try adjusting flow direction and intensity.
- Wrong lighting for the type: NPS gorgonians placed under intense reef lighting will keep polyps closed during the day. Reduce light and observe at night.
- Shipping stress: After any gorgonian arrives by mail, expect 1–2 weeks before it's fully expressing in its new environment.
Problem 3: Tissue Recession
What it looks like: Bare skeleton becoming visible as tissue pulls back from one area — typically starting at the base or tips of branches.
Causes: Poor water quality, inadequate flow, physical damage to tissue, or bacterial infection.
What to do:
- Check and correct all water parameters immediately.
- Verify flow is reaching the coral consistently.
- For bacterial infection (reddish or blackish band moving across the skeleton), try an iodine dip.
- Frag healthy branches immediately. If recession is progressing, cut healthy sections away from the affected area and re-anchor them on clean substrate. The healthy frags can re-establish as new colonies. Waiting too long means losing the entire piece.
If recession is progressing steadily upward from the base despite good water quality and flow, the coral is unlikely to recover in that form — fragging and saving healthy branches is the best outcome available.
Problem 4: Gorgonian Still Closed After Purchase — Is It Dead?
A gorgonian that has just arrived by mail and isn't opening is almost certainly not dead. It is almost certainly stressed from shipping.
How to check:
- Does it smell like clean ocean water, or does it smell rotten? If it smells fresh, it's alive.
- Is the tissue still attached to the skeleton? Healthy tissue looks intact and connected; dead tissue peels or falls away.
- Are there no polyps extended anywhere on the whole coral?
Give a freshly arrived gorgonian 7–14 days of stable, well-flowing water before drawing any conclusions. Gradual acclimation to your tank's specific lighting and chemistry takes time. Resist the urge to move it, test it, or "help" it by changing conditions rapidly. Stability is the cure.

Gorgonian Coral FAQ
These are the most commonly asked gorgonian questions in reef forums, AI search platforms, and aquarium communities. Direct answers below.
Are gorgonians hard to keep?
Caribbean photosynthetic gorgonians — including Purple Frilly, Corky Sea Fingers, Tan Rod, Purple Whip, and Green/Yellow Whip — are genuinely beginner-friendly in a running reef system. They need moderate to high lighting, strong alternating flow, and occasional supplemental feeding. Non-photosynthetic gorgonians require daily feeding and expert-level management — they are not beginner corals.
What is the difference between photosynthetic and non-photosynthetic gorgonians?
Photosynthetic gorgonians contain zooxanthellae algae in their tissue and derive most of their energy from light, similar to most reef corals. Non-photosynthetic gorgonians contain no algae and must be fed every day with fine particle foods like phytoplankton, rotifers, and baby brine shrimp — they get no energy from light at all.
How do I tell if a gorgonian is photosynthetic?
Look at the polyp color. Brown or tan polyps almost always mean photosynthetic. Bright white, orange, red, yellow, or blue polyps typically mean non-photosynthetic. Branch color is a secondary clue: muted tans and purples are usually PS; vivid reds and yellows are usually NPS. Always confirm with your seller before purchasing.
Do gorgonians need to be fed?
Photosynthetic gorgonians don't need feeding to survive, but weekly supplemental food (marine snow, zooplankton, phytoplankton) improves growth and color. Non-photosynthetic gorgonians must be fed daily with fine foods like baby brine shrimp, rotifers, and phytoplankton — without it, they will decline and die.
What lighting do gorgonians need?
Photosynthetic gorgonians need moderate to high reef lighting — they are shallow Caribbean water species and are adapted to bright sunlight. Non-photosynthetic gorgonians need low to no direct light. Intense light on NPS species promotes algae growth on branches, which smothers the tissue.
What flow do gorgonians need?
All gorgonians — photosynthetic and non-photosynthetic — require moderate to strong, alternating or intermittent water flow. Flow prevents algae and cyanobacteria on branches, delivers food particles, and replicates natural wave surge. Insufficient flow is the primary cause of gorgonian failure in home aquariums.
Are Caribbean gorgonians easier than Pacific gorgonians?
Yes, significantly. Most Caribbean gorgonians in the aquarium trade are photosynthetic, shallow-water species adapted to conditions that closely match a standard home reef tank. Most flashy Pacific gorgonians are non-photosynthetic, deep-water species that require expert care and dedicated systems. For beginners or intermediate reef keepers wanting gorgonians, Caribbean species are the correct starting point.
Why is my gorgonian covered in algae?
Almost always caused by insufficient water flow. Increase flow first. If cyanobacteria has established, remove the coral and do a brief freshwater dip (same temperature, under two minutes) to kill the bacteria. For attached algae, use a very soft brush gently while the coral is submerged. Prevent recurrence with strong alternating flow and appropriate nutrient control.
Why are my gorgonian's polyps closed?
The most common reasons are: (1) new arrival stress — give it 7–14 days, (2) poor water quality — test and correct parameters, (3) incorrect flow — adjust direction and intensity, (4) lighting mismatch — NPS gorgonians will close during the day under strong light and open at night. Check each variable systematically before assuming the coral is in serious trouble.
Can gorgonians be kept with seahorses?
Yes — Caribbean gorgonians are among the best natural hitching posts for seahorses and are specifically recommended in seahorse aquarium setups. Photosynthetic types like Green/Yellow Whip and Tan Rod are most practical because they don't require the dedicated daily feeding that NPS species do. Seahorses and gorgonians make a natural, ecologically accurate pairing — both are found together on Caribbean reefs.
How do I anchor a gorgonian in my reef tank?
Apply reef-safe super glue gel or two-part epoxy to the gorgonian's base and press firmly against live rock or rubble for 20–40 seconds. The coral's tissue will gradually grow over the adhesive and bond naturally to the substrate. Position in your desired location before applying adhesive — repositioning later is more stressful for the coral.
Do gorgonians grow fast?
No — gorgonians are slow growers, typically adding a few centimeters per year. Stable parameters, proper lighting for the type, consistent flow, and regular feeding will maximize growth rate. Encrusting species like Corky Sea Fingers spread faster than branching types.
What do gorgonians eat?
Photosynthetic gorgonians primarily photosynthesize but eat small zooplankton, phytoplankton, and marine snow as a supplement. Non-photosynthetic gorgonians are carnivorous filter feeders that eat baby brine shrimp, rotifers, copepods, fine frozen foods, and liquid coral foods daily.
Are gorgonians reef safe?
Generally yes, with some caveats. Most gorgonians are peaceful to other reef animals. Semi-aggressive species (Purple Frilly, Purple Bush, Purple Rod) can sting neighboring corals with their tissue if placed too close — maintain buffer spacing. Encrusting species like Corky Sea Fingers will overgrow adjacent soft corals if they spread unchecked. Otherwise, gorgonians are not predatory toward fish, inverts, or corals.
What are the best beginner gorgonians?
From the species we carry at Foxy, the best beginner choices are:
- Corky Sea Finger — hardiest, easiest, most forgiving
- Tan Rod / Rusty Rod — hardy, tree-like structure, moderate care
- Green/Yellow Whip — photosynthetic, minimal feeding needed, great for seahorse tanks
- Purple Frilly — beautiful and manageable with consistent flow
Should You Buy a Photosynthetic or Non-Photosynthetic Gorgonian?
| Parameter | Photosynthetic (Caribbean) | Non-Photosynthetic (NPS) |
|---|---|---|
| Skill Level | Beginner to intermediate | Advanced to expert |
| Lighting | Moderate to high | Low to none |
| Feeding | Optional (1–2x/week supplemental) | Mandatory (daily) |
| Temperature | 72–82°F | 68–75°F — often needs chiller |
| Best Foxy Picks | Corky Sea Finger, Tan Rod, Green/Yellow Whip, Purple Frilly | Red Finger, Yellow Finger, Colorful Sea Whip |
| Risk Level | Low to moderate | High |
| Reef Safe | Yes (with spacing) | Yes |
| Good for Seahorse Tanks | Yes — excellent hitching posts | Possible but demanding |
For most reef keepers, start with a Caribbean photosynthetic species. Get comfortable with gorgonian flow and lighting requirements before considering NPS species. Add non-photosynthetic gorgonians only once you have a stable, mature system and a reliable daily feeding routine in place.
Where to Buy Caribbean Gorgonian Coral
At Foxy Saltwater Tropicals, approximately 90% of our Atlantic and Caribbean products are hand-collected by our own team from the waters of the Florida Keys. That means when you buy a Purple Whip, a Red Finger, or a Corky Sea Finger from us, it has gone from the reef to our holding tanks to your door — with minimal stress and maximum accountability at every step.
We know the depth our corals come from, the conditions they were collected in, and what their specific care requirements are because we've observed them in their natural habitat. No middleman, no guesswork.
