Description

The convict blenny is a remarkable, eel-shaped reef fish from the Western Pacific. The species grows to about 34 cm; juveniles are black with a yellow stripe and swim in dense, writhing schools resembling a venomous snake, while adults are black-and-white banded (hence 'convict'). It digs extensive burrow systems in sand and rubble under coral, in which the whole colony shelters, and feeds on zooplankton at night. The fish is harmless to humans and appears in the reef aquarium. The IUCN has not evaluated the species.
