Butter Hamlet

The Caribbean Butter Hamlet (Hypoplectrus unicolor) is a beautifully subtle and personality-filled addition to saltwater aquariums. Known for its smooth golden-yellow to buttery tan coloration and compact grouper-like body, this species adds understated elegance and classic Caribbean reef charm to your tank.

Native to Caribbean reefs and rocky areas, Butter Hamlets appreciate plenty of live rock with caves and ledges where they can perch and feel secure. They are generally peaceful toward similarly sized fish but can be territorial with other hamlets or very small tank mates.

This species is hardy and adapts well to captivity, readily accepting a carnivorous diet of meaty frozen foods such as mysis shrimp, brine shrimp, and finely chopped seafood, along with high-quality prepared foods. Its manageable size, calm demeanor, and unique coloration make it a great choice for hobbyists with established reef or fish-only systems.
