Common name: Disco blenny

General information

The Forktail Blenny, scientifically known as Meiacanthus smithi, is a small and active fish that is well-suited for the community reef aquarium. It is part of the Blenniidae family and is known for its distinctive forked tail and the ability to deliver a mild venom through its fangs as a defense mechanism. This venom is not dangerous to humans but can deter predators in the wild.

These blennies are not only appreciated for their interesting behavior and appearance but also for their role in controlling algae in the aquarium. They are a peaceful species that can coexist with a variety of tank mates, but care should be taken to avoid housing them with aggressive fish that may provoke them.

Care

Forktail Blennies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for grazing and hiding. A varied diet that includes both plant and animal matter will help maintain their health and coloration. It's important to provide a tightly sealed lid, as these fish are known jumpers.

Reproduction

In the home aquarium, breeding Forktail Blennies can be a challenging but rewarding experience. They are oviparous, with males often displaying territorial behavior during breeding. The male will guard the fertilized eggs, which are typically laid in a secure location within the live rock.

Habitat

Meiacanthus smithi is found in the Western Pacific, particularly around the Great Barrier Reef and Coral Sea. They inhabit shallow reef environments, often in areas with strong currents where they can be seen darting in and out of the reef structure.
