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.
