Scientific name: Meiacanthus oualanensis (Günther, 1880)

General information

The Forktail Blenny, scientifically known as Meiacanthus oualanensis, is a small, vibrant fish that is popular among reef aquarium enthusiasts. This species is known for its distinctive yellow and black coloration and the forked appearance of its tail. One of the most interesting features of the Forktail Blenny is its ability to deliver a mild venom through its fangs, a unique adaptation among blennies that it uses for defense.

Care

Forktail Blennies are relatively easy to care for, making them suitable for both beginner and advanced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing on microalgae. It's important to provide a varied diet that includes marine algae, vegetable matter, and meaty foods to maintain their health and coloration.

Reproduction

In the home aquarium, breeding Forktail Blennies can be a rewarding experience. They are oviparous, with males often displaying to attract females and encourage them to lay eggs in a secure location. The male then guards the eggs until they hatch.

Symbiosis

While not known for any specific symbiotic relationships like those seen in clownfish and anemones, Forktail Blennies do play a role in the reef ecosystem by controlling algae growth and providing a food source for larger predators.

Habitat

Meiacanthus oualanensis is native to the coral reefs of the Western Pacific, where it is typically found in shallow waters. They prefer reef environments with plenty of crevices and overhangs to provide shelter and foraging grounds.
