				Adults inhabit silty lagoon and coastal reefs around coral outcrops and seagrass beds (Ref. 9710).  Often adjacent to clear mangrove coasts among rubble and Sargassum algae, to a few meters depth (Ref. 48636).  Oviparous, distinct pairing during breeding (Ref. 205).  Eggs are demersal and adhere to the substrate (Ref. 205).  Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 52881).
