Breeding habits

This fish is monomorphic: males and females are not visually different (males are bigger) and form small colonies or harems—depending on available space—in which the male fry are tolerated until they become active competitors of the male. Female fry are not only tolerated but are eventually courted as mates. The females also are objects of interest to neighboring males and may be targets of theft.
