Common name: Threadless blenny
General information
The Forktail Blenny, scientifically known as Meiacanthus anema, is a small and active fish that adds both character and utility to a saltwater aquarium. Its most distinctive feature is the forked tail from which it gets its common name. This species is part of the Blenniidae family and is known for its ability to deliver a mild venom through its fangs—a unique adaptation for defense.

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 perching and hiding. These fish are omnivorous and will accept a variety of foods, but a diet that includes marine algae and meaty foods will help maintain their health and coloration.
Reproduction
In the wild, Forktail Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, but with the right conditions and a well-maintained breeding tank, it is possible for hobbyists to witness their fascinating reproductive behavior.
Symbiosis
While not involved in the classic symbiotic relationships seen in some marine species, Forktail Blennies do play a role in the control of nuisance pests, such as bristle worms, by preying on them. This can be beneficial in maintaining the ecological balance within the aquarium.
Habitat
Meiacanthus anema is native to the Western Pacific, where it is typically found in shallow, coral-rich areas and lagoons. They are adept at navigating the complex structures of coral reefs and are often observed darting in and out of crevices.
