The Canary Blenny is also known as the Oualan Forktail
Blenny, or Canary Fang Blenny. The Canary 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 Blenny will retaliate by biting the inside of the mouth of the attacker.
The Canary 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 Blenny should consist of finely chopped crustacean flesh, mysis and
vitamin-enriched brine shrimp as well as frozen herbivore preparations
