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.
