Sailfin Catfish

Found singly, amongst debris, in crevices and holes, under ledges and rocks of shallow coastal reefs.
They are bottom feeders and use the barbels around their mouth to detect food.
They feed on crustaceans and molluscs.
Juveniles form tightly packed schools for feeding which may contain hundreds of fish.

Catfish have venomous spines in the fins which can inflict painful wounds.
Repeated stings from these catfish may result in death.
