Pomacentridae primarily inhabit tropical reef habitats. Some live along steep edges of the reef, and others in sandy sheltered lagoons. In each ocean a few species occupy warm temperate waters, and three estuarine species can sometimes be found in fresh water. Some school in the water column, some live on rocky areas or sea-grass beds, and fishes of the subfamily Amphiprionina (anemonefishes) always dwell in association with sea anemones. A few deep-water species occur at the edge of the shelf at depths below 100 m, but most pomacentrids occupy shallow water between two and 15 meters deep.
