Common name: Two-striped fangblenny

General information

The Forktail Blenny, scientifically known as Meiacanthus ditrema, is a distinctive and charming species popular among aquarists for its unique appearance and behavior. This species is part of the Blenniidae family, known for their elongated bodies and bold personalities. The Forktail Blenny is particularly noted for its forked tail and the striking coloration that often includes shades of blue, yellow, and white.

One of the most fascinating aspects of the Forktail Blenny is its ability to deliver a mild venom through its fangs, a defense mechanism against predators. This feature makes them one of the few venomous fish available to hobbyists, but the venom is not dangerous to humans and is primarily a concern for tank mates.

Care

Forktail Blennies 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. These fish are known to be jumpers, so a well-fitted aquarium lid is essential to prevent escape. They thrive in a stable environment with consistent water quality and benefit from a varied diet that includes both meaty foods and algae-based preparations.

Reproduction

In the wild, Forktail Blennies are oviparous, with males often displaying territorial behavior during breeding. They lay adhesive eggs that are attached to the substrate or rock surfaces. In the aquarium, breeding these fish can be challenging, but with careful attention to water quality and diet, it is possible for hobbyists to witness their fascinating mating rituals and care for the developing fry.

Habitat

Meiacanthus ditrema is found in the Western Pacific, inhabiting shallow reefs and lagoons. They prefer areas with abundant coral growth and rockwork, where they can easily dart in and out of hiding spots. Their natural habitat often includes strong currents, which should be replicated in the home aquarium to some extent for their well-being.
