Blue Hamlet (Hypoplectrus gemma)
The Caribbean Blue Hamlet (Hypoplectrus gemma) is a striking and colorful addition to saltwater aquariums. Known for its rich, deep blue body and compact, grouper-like shape, this species brings vibrant color and classic Caribbean reef charm to your tank.
Native to Caribbean reefs and rocky habitats, Blue 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 makes it ideal for mid-sized reef tanks.

Added a Blue Hamlet to my 55-gallon reef tank last month. It’s very active and colors stand out in the tank. I provide mysis shrimp daily and it eats well. The fish seems comfortable in the caves I built. Good choice for a colorful, low-maintenance reef fish.

The Blue Hamlet looks stunning in my tank. I’ve had it for about two months and it’s adapted well to the diet and environment. I keep it with a few peaceful tangs and it’s not showing signs of aggression. Just make sure there are enough hiding spots.

I was worried about compatibility, but the Blue Hamlet has been peaceful since I introduced it. It’s active during the day and enjoys the live rock. Feeds easily on frozen foods. A great addition to a mid-sized reef setup.
