Appearance and identification

The scaleless area between the eyes and over the forehead is the feature referred to by the name calvus.

Social behaviour and territory

Can be kept as a pair or one male with multiple females. Provide more rock caves than occupants; this is not a tight-schooling fish.

Diet and feeding

Mainly suitably sized live and frozen animal foods. Some fish accept dried foods; confirm that each individual feeds.
