Canary Blenny

Canary Blenny

Meiacanthus oualanensis

Identification The Canary Blenny is a striking, entirely bright yellow fish with a slender body and a large head. It belongs to the fang blenny family and has modified canine teeth capable of delivering a mild venomous bite — primarily a defense against predators. Its bold yellow coloration serves as a warning signal.

Reef Compatibility Reef safe

Behavior

A peaceful and active fish that spends most of its time swimming in the lower and middle areas of the tank. It is generally non-aggressive toward other species but may quarrel with other fang blennies. Its venomous bite deters most predators, making it a confident and unafraid swimmer. Provide plenty of live rock with crevices and holes for shelter and perching.

Diet & Feeding

Omnivore. In the wild it feeds on small crustaceans, copepods, zooplankton and algae. In captivity it readily accepts frozen mysis shrimp, brine shrimp, finely chopped meaty foods and high-quality flake or pellet foods. Feed 2–3 times daily.

Cautions

Its venomous bite is a defense mechanism — it will bite if mishandled. Do not house with other fang blenny species unless the tank is very large. A tight-fitting lid is recommended as it may jump.
