Hamlets are rather uncommon in aquariums even though they are often strikingly beautiful and easy to maintain. Blue and Indigo hamlets are commonly offered in the aquarium trade, and both have brilliant blue coloration. These hardy fish are rather timid and will often hide in rocks and caves during the day.
Hamlets are from the Serranidae family and genus Hypoplectrus and are related to groupers and anthias. There are only 10 fish in the Hypoplectrus genus although some similar fish may also have "hamlet" as part of their scientific name (most notably the considerably larger Mutton Hamlet, Alphestes afer). They are from the western Atlantic Ocean and Caribbean; a contrast from many other aquarium fish that come from the Indo-Pacific region.
Hamlets are known to be aggressive towards other hamlets or basses, but are rarely aggressive towards other species. Occasionally, they are attacked by more belligerent fish like groupers and they are known to prey on smaller fish or on invertebrates like crabs and shrimp.
