The blacktip grouper grows up to 40cm in length and may weigh up to 2kg. The tips of the spines of the dorsal fin are black, and it may have a dark red cap above the eyes. There is a variant with a uniformly pale body except for the frontal part.
It is found associated with coral reefs from 4m deep (more commonly from 15m) up to 160m, in both marine and brackish water, sometimes in groups of 10-15 individuals. Juveniles may find shelter in mangrove swamps.
