Canary Blenny



The Canary Blenny is also known as the Oualan Forktail Blenny or Canary Fang Blenny. This Canary Blenny is aptly named due to its vibrant yellow. Males tend to be larger than females, and they experience an array of color variations during breeding. This blenny requires a tank size of at least 30 gallons filled with live rock for hunting and grazing to flourish. It is best to have just one per tank, unless a breeding pair. If the fish is attacked it responds by slicing into the attacker's mouth. The Canary Blenny is considered venomous and should be handled carefully in the presence of children who have access to tank.   Canary Blenny's diet should consist of minced crustacean flesh as well as mysis, vitamin enriched brine shrimp and frozen herbivore dishes.   Approximate Purchase Size: Small: 1-1/4" to 2-1/2"; Medium: 2-1/2" to 3-1/4"; Large: 3-1/4" to 4"

The blenny requires a medium to a large tank with live rocks to hunt and graze in order to flourish. It is recommended to keep one in each tank unless there is a breeding pair. If the fish is attacked by another the Canary Blenny will respond by slicing into the mouths of its attacker. This blenny species is considered venomous and should be handled at a safe distance from children with access to tanks as it could consider fingers to be an attack and then deliver a similar painful bite.

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
