General information

The Striped Fang Blenny, Meiacanthus grammistes, is a distinctive and interesting species in the Blenniidae family. Known for its bold black and white stripes, this small fish is a favorite among aquarists for its personality and relatively peaceful nature. It is one of the few fish species that possess venomous fangs, which it uses primarily for defense against predators rather than for hunting prey.

Care

Caring for Striped Fang Blennies is moderately easy, making them suitable for intermediate aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. It's important to provide a varied diet that includes meaty foods and marine algae to maintain their health. They are generally peaceful but can be territorial towards their own kind or similar-looking species.

Reproduction

In the home aquarium, breeding Striped Fang Blennies can be a challenge. They are oviparous, with the female laying eggs in a secure location which the male then fertilizes. The male guards the eggs until they hatch. Success in breeding requires a separate breeding tank and experience in rearing larval fish.

Symbiosis

While not known for a specific symbiotic relationship like clownfish with anemones, Striped Fang Blennies do play a role in the ecosystem by controlling algae growth and potentially reducing the spread of parasites through their cleaning behavior.

Habitat

Striped Fang Blennies are found in the Indo-Pacific region, from the Red Sea and East Africa to the Line, Marquesan, and Society Islands, north to southern Japan, and south to New Caledonia. They inhabit coral reefs and lagoons, often seen darting among the crevices and overhangs.
