Meiacanthus atrodorsalis – The Forktail Blenny is an outgoing, curious species of fang blenny. Most blennies are shy and hide most of the time, but not the Forktail Blenny. It’s extra gregarious because it doesn’t have much to worry about due to its secret weapon – venomous fangs. It’s extremely rare for aquarists to receive a bite; just be careful not to accidentally squeeze or harass your blenny. In the wild if a fish tries to gobble them, they inflict a painful bite, and the fish (hopefully) releases them. This confidence allows them to swim out in the open, interacting with and entertaining their humans.
This is an incredibly hardy and reef safe species with beautiful coloration and lots of personality. They do well in small tanks of 30 gallons or more singly, in pairs, or in small groups in larger aquariums.
