Not Reef Tank Suitable
Likely Fish-Only Tank Suitable
These fishes belong in the Order Perciformes and Suborder Percoidei, and are members of the Family Serranidae (Groupers & Anthias). These benthic Reef Basslets are in the Genus Liopropoma, with many looking similarly shaped and occupying similar habitats. They are also quite diverse location-wise and occur in the Indian, Pacific, and Atlantic Oceans. Since they keep close to the substrate, they may do better in reef-like environments.
Reef Basslets are a deeper water species and come out to feed at dusk. They are quite secretive and difficult to catch in the wild. Usually shy when first placed in the aquarium and should have many hiding places. Keep in mind they may eat small crustaceans. They are prone to hiding if kept under bright lighting.
