Solitary (Ref. 26340) and secretive, they usually stay near hiding places during the day. Prefer to remain within a small area of the home range of about 2,120 square m especially during the day (Ref. 56524). Nocturnal predators, adults feed mainly on fishes, with preference on Chromis multilineata, while juveniles feed on shrimps. Due to its small size, this is not a particularly sought-after species. Easily approached and fed by divers (Ref. 9710). Protogynous (Ref. 26938). Between 1995 and 2000, at least 10 specimens have been traded as aquarium fish at Ceará, Brazil (Ref. 49392).
