The Canary Fang Blenny is also known as the Oualan Forktail Blenny, or Canary Blenny. The Canary Fang Blenny is aptly named, being a solid vibrant yellow. Males are generally larger than females and experience a succession of color changes when breeding.

This blenny needs a minimum tank of 30 gallons with live rock for hunting and grazing in order to thrive. It is best to keep only one per tank unless a breeding pair is maintained. If attacked by other fish, the Canary Fang Blenny will retaliate by biting the inside of the mouth of the attacker. The Canary 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 of the Canary Fang Blenny should consist of finely chopped crustacean flesh, mysid and vitamin-enriched brine shrimp, as well as frozen herbivore preparations.
