The Blue Head Fang Blenny has a caudal fin that resembles a fork, with two long exterior spines and five much shorter middle spines. The body is a pale blue that runs like watercolour into a bluish-yellow at the tail. Males are generally larger than females and experience a succession of colour changes when breeding.

The Blue Head Fang Blenny needs a minimum tank of 30 gallons with live rock for hunting and grazing. It is best to keep only one per tank unless a breeding pair is maintained. The Blue Head Fang Blenny is considered venomous and should be kept only with caution around children having tank access since it may perceive fingers as an attacker and deliver a similarly painful bite.

The diet should consist of finely chopped crustacean flesh, mysis and vitamin-enriched brine shrimp, as well as frozen herbivore preparations.
