About the Canary Blenny

The canary blenny is a fang blenny, bright yellow from head to tail, that reaches about 4 to 5 inches. It is reef safe, gets along with most fish and eats small meaty and herbivore foods two or three times a day. Like its relatives it has venomous fangs that it uses only in defense, so never hand feed it. Keep one per tank unless you have a pair, give it rockwork with holes to claim and keep the tank covered, because it jumps.
