Canary Blennies (Meiacanthus oualanensis), is also known as the Oualan Forktail Blenny, or Canary Fang Blenny, are a small, colorful saltwater fish that are popular among hobbyists due to their unique appearance and playful behavior. In this care guide, we'll cover everything you need to know to keep your Canary Blenny healthy and happy in your aquarium.

Habitat and Tank Requirements

Canary Blennies are native to the Western Pacific, including the waters around Indonesia, the Philippines, and Papua New Guinea. In an aquarium, they require a minimum tank size of 30 gallons with plenty of live rock and hiding places.

Water parameters should be kept stable, with a temperature range of 72-78°F, a pH between 8.1-8.4, and a salinity of 1.023-1.025. Proper filtration and regular water changes are also essential for the health of your fish.


Canary Blennies are omnivorous and require a varied diet of high-quality frozen or live foods. They primarily feed on small crustaceans and zooplankton found in the sand or rock crevices. A diet consisting of brine shrimp, mysis shrimp, and chopped squid or shrimp is ideal for Canary Blennies.

Behavior and Tank Mates

Canary Blennies are a peaceful fish and can be kept with other peaceful fish and invertebrates. However, they may become territorial and aggressive towards other blennies or fish that are similar in appearance or behavior.

These fish are active swimmers and require plenty of open swimming space, as well as live rock and coral for hiding places. They may also burrow in the sand, so it's essential to have a substrate that's suitable for digging.


Canary Blennies have been bred in captivity, but it can be challenging to distinguish between males and females. If you're interested in breeding these fish, it's important to provide a peaceful environment and plenty of hiding places for the female to lay her eggs.

Once the eggs are laid, the male will fertilize them and guard the nest until they hatch. The fry can be fed a diet of rotifers and small crustaceans until they are large enough to eat adult food.


Canary Blennies are a colorful and playful addition to any reef aquarium. By providing a peaceful environment, a varied diet, and suitable tank mates, you can ensure that your Canary Blenny is healthy and happy in your aquarium. Keep an eye on water parameters and provide regular care to keep your fish thriving. With patience and dedication, you can enjoy the vibrant beauty of this unique fish in your aquarium.
