ORA® Captive-Bred Canary Blenny

Greek Name: Meiacanthus oualanensis



The ORA® Captive-Bred Canary Blenny is also known as Oualan Forktail Blenny or Canary Fang Blenny. It is appropriately named because it’s a bright, vibrant yellow. Males are typically larger than females, and they experience several color shifts during breeding.
The blenny requires the minimum tank size of 30 gallons and reef rock to hunt and graze to flourish. It is recommended to keep only one in each tank unless the breeding pair is kept. If a fish is attacked by another the ORA® Captive-Bred Canary can retaliate by biting inside its mouth to ward off the one who is attacking. This Blenny is regarded as poisonous and should be handled with care when children are near tanks as it can detect fingers as an attack and then deliver a painful bite.


A diet for Canary Blenny should consist of a wide variety of minced crustacean flesh that has been finely chopped. Mysis, vitamin-enriched brine shrimp, as an addition to frozen herbivore recipes.

General information about Canary Blenny
The Canary Blenny is appropriately named, as it is an intense yellow color. This blenny requires a moderately large tank with live rocks to hunt and graze for them to flourish. It is recommended to only keep one in each tank unless there is a breeding pair. If a fish is attacked by another this reef aquarium fish will respond by slicing into the mouth. It is believed that the Canary Blenny is considered venomous and should be treated at a safe distance from children with access to tanks as it could consider fingers to be an attacker and then deliver a painful bite.
