General Info

Pomacentridae family consists of 28 genera and 321 species. Abundant over reefs. Hide in coral or crevices when danger approaches. Some species are very territorial. The male builds a ‘nest’ on rock and the female lays her eggs there, which is in turn fertilised by the male. The male guards the nest for up to seven days.


Depending on their habitat, they will feed on algae, plankton, corals and small bottom- dwelling crustaceans.


Occurs in all temperate and tropical oceans of the world.
