Assessors

These members are shy, retiring, and mouthbrooders, and should be kept in an aquarium with numerous hiding places. Do not keep with fishes or crustaceans small enough to be eaten.

Calloplesiops

They spend their daylight hours in caves with only their tail possibly protruding outward. Their tail contains a false eyespot and gives the fish a moray eel appearance, which discourages predators. They require a calm environment, are not aggressive feeders, and feed on small live fishes or shrimp. Do not keep them with fishes small enough to be eaten.
