Description

A slender, solid canary-yellow fangblenny with a deeply forked (lunate) tail whose lobes elongate in large adults, it hovers openly in the water column rather than perching on rock like most blennies. It is hardy and reef-safe, ignoring corals, clams and ornamental invertebrates, but can be territorial toward other blennies, gobies and dartfish, so keep one per tank unless you have a proven pair. Provide mature live rock for grazing and hiding, feed small meaty and algae-based portions 2-3 times daily, and use a tight-fitting lid because it is an accomplished jumper; its grooved venomous canines make it largely predator-proof but capable of a painful bite during maintenance.

Reef Safe

Yes

Environment

The Canary Blenny prefers a tank with plenty of hiding spots and a sandy substrate to mimic its natural habitat. It also needs clean, well-aerated water.

Behavior

This species is generally peaceful but can be territorial with other blennies, especially in smaller tanks. It is known for its unique ability to "hop" along the bottom of the tank using its pectoral fins.
