Common name: Swallowtail fangblenny

Scientific name: Meiacanthus procne Smith-Vaniz, 1976

General information

The Blackline Fangblenny, Meiacanthus procne, is a small, colorful fish known for its distinctive black lateral line and its ability to deliver a venomous bite. This species is part of the Blenniidae family, which includes blennies with elongated bodies and a characteristic pair of canine teeth at the front of their lower jaws. These teeth are associated with venom glands that can deter predators.

In the wild, Meiacanthus procne is often found in shallow, coral-rich environments where it can easily dart in and out of crevices for protection and foraging. Its vibrant coloration and active behavior make it a popular choice for reef aquariums.

Care

Blackline Fangblennies are relatively hardy and can adapt to life in captivity. They require an aquarium with plenty of live rock for hiding and grazing on microalgae. It's important to provide a varied diet that includes meaty foods and marine algae to maintain their health and coloration.

While generally peaceful, they can be territorial with their own kind and similar species. It's best to keep them singly or in a mated pair, and they should be introduced into the aquarium at the same time to reduce aggression.

Reproduction

In the aquarium, breeding Blackline Fangblennies can be a challenge. They are oviparous, with the female laying adhesive eggs that are then fertilized by the male. The male guards the eggs until they hatch. Successful breeding requires excellent water quality and a well-established aquarium.

Habitat

Meiacanthus procne is native to the Western Pacific, including the Great Barrier Reef, Coral Sea, and reefs around Papua New Guinea. They are typically found at depths ranging from the surface to about 25 meters, often in lagoons or on outer reef slopes.
