Description

The bicolor fangblenny is a small sabretooth blenny from the Western Pacific. The species grows to about 8 cm and has an elongate body that is dark in front and yellow behind, a mimic of the venomous Meiacanthus fangblenny. Thus protected, it swims freely around the reef and snatches scales, mucus and skin from larger fish. In the lower jaw it bears large canines. The fish is largely harmless to humans but can nip when caught. The IUCN has not evaluated the species.
