Shaving Brush

These easy to care for marine plants grow in sandy substrates and have excellent filtration capacity for nitrates and phosphates. The plant actually resembles a green shaving brush that is used to apply shaving cream. Long thin leaves extend from the center stalk creating that brush or feather like appearance. It's an attractive addition to your fish tank or aquarium or refugium. They do require a nice amount of light for healthy growth and will benefit from the addition of calcium and iron supplements. Herbivorous fish will not consume Shaving Brush plants, however there are some sea urchins may actually feed on these plants. 

Mermaid Fan Plant

The Mermaid Fan Plant (Udotea) is another easy to care for marine plant. It has a bright green color and typically grows to about 8" in height. This type of algae is common to the Caribbean. It will grow in sand and will also attach to live rock and coral. This plant is composed of calcium carbonate. Although mermaid fans are hardy plants, pruning is not recommended. Their diet consists of nitrates and phosphates found naturally in your tank water, but they will also require some calcium supplements and plenty of lighting to ensure optimal growth. Make sure when you plant them in your refugium or tank, that they have access to direct light. Most fish will not consume this particular plant.


Halimeda is a green macroalgae whose tissue contains calcium carbonate. Halimeda grows in tropical oceans both in shallow and deep water. The main root of the plant will attach to any sandy substrate or live rock found in your aquarium. It's typically referred to as Cactus algae because it looks like a prickly pear cactus - it has flat segments that join to together much like a pricky pear cactus. Halimeda grows slowly and maximum growth height is about 4". For a healthy plant, we recommend calcium supplements, carbon dioxide and aquarium fertilizer. If their leaves turn white, don't panic, segments of this algae will sometimes die and the white is the calcium carbonate from their tissue.

    Neat marine plant

    Posted by John Pittenger on 24th Oct 2016

    I ordered 3 of these and they came well wrapped and packaged. Received 3 of the shaving brushes and spread them out in my tank. A very unique and well named plant. They really do look like a shaving brush.
