Inhabits the sediment-rich regions and is often found over sandy and muddy patches between rocks. Abundant in waters > 10 m (Ref. 6256). Feeds by brushing the loose algae from the rocks and also on plankton in open water (Ref. 5595). Aggressive males exhibit territoriality over sand-dug nests. Females, juveniles and non-territorial adult males occur singly or in small groups (Ref. 6256). All males have only one eggspot on the anal fin (Ref. 47814).
Levenscyclus en paargedrag

Females are mouthbrooders (Ref. 2060). Males adorn one eggspot on the anal fin which mimics eggs and apparently functions to lure females to pick up this egg enabling fertilization of the rest of the eggs being brooded in the females's mouth (Ref. 47814). In one experimental study, females are attracted to males with one large eggspot more than to those with numerous tiny eggs covering the same area (Ref. 47814).
