The blacktip grouper or redbanded grouper, Epinephelus fasciatus, is a species of marine fish in the family Serranidae.[2]


The blacktip grouper is widespread throughout the tropical waters of the Indo-Pacific area from the Red Sea to South Africa, as far north as Korea, and in the waters around Australia to Pitcairn Islands.[3] It is also commonly found around the Mascarene_Islands and is a prized commercial fish in Mauritius.


The blacktip grouper grows up to 40 cm in length and may weigh up to 2 kg, but its common size is average 22 cm.[3] The tips of the spines of the dorsal fin are black, and it may have a dark red cap above the eyes.[4][5] A variant occurs with a uniformly pale body except for the front part.[6]

It feeds on crustaceans and smaller fishes by ambushing them.[3][5] It is found associated with coral reefs from 4 m deep (more commonly from 15 m) up to 160 m, in both marine and brackish water, sometimes in groups of 10-15 individuals.[3][5] Juveniles may find shelter in mangrove swamps.[6]

Blacktip groupers of the Red Sea are fished by the Bedouin.[6] It has also been associated with ciguatera poisoning.[3]

Philometra fasciati (Nematoda, Philometridae), a parasite of the ovary of the blacktip grouper

Blacktip groupers are host of several parasites, including Pseudorhabdosynochus spp. (diplectanid Monogeneans) on the gills.[7] The philometrid nematode Philometra fasciati is parasitic in the ovary of female fish;[8] the adult female parasite is a red worm which can reach up to 40 centimetres in length, for a diameter of only 1.6 millimetre; the males are tiny.
