Barred Hamlet (Hypoplectrus puella)
The Caribbean Barred Hamlet (Hypoplectrus puella) is a striking and personality-filled addition to saltwater aquariums. Known for its pale body accented by bold vertical black bars, this small grouper relative adds dramatic contrast and a classic Caribbean reef look to your tank.
Native to Caribbean reefs and rocky outcrops, Barred Hamlets appreciate plenty of live rock with caves and overhangs where they can perch and feel secure. They are generally peaceful toward similarly sized fish but can be territorial with their own kind 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 marine pellets.

The Barred Hamlet is a beautiful addition to my reef tank. It’s active and curious, and the black bars stand out beautifully against the pale body. I provide plenty of live rock and it uses the caves well. Feeds easily on frozen mysis and brine shrimp.

It’s a striking fish with a classic look. I noticed it’s a bit territorial with two other small fish, so I adjusted the tank layout to give it more space. Overall, it’s a great choice for a reef setup with proper hiding places.

Easy to care for and very active. I’ve been keeping it for six months and it’s still healthy and vibrant. The diet is simple—just a mix of frozen foods and marine pellets. It’s a real eye-catcher in the tank.
