The Blacktip Grouper (Epinephelus fasciatus), is a member of the Serranidae, the family which includes the sea basses as well as the groupers. It is widely distributed and found from the Red Sea to South Africa, as far north as Korea, and in the waters around Australia. It is found associated with coral reefs from 15 feet up to 525 feet in depth, in both marine and brackish water, sometimes in groups of 10-15 individuals. Juveniles may find shelter in mangrove swamps.
The Blacktip Grouper grows up to 15.75 inches in length and may weigh up to 4.4 pounds. 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 feeds on crustaceans and smaller fish by ambushing them.
