Forktail Blenny (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.

The Forktail Blenny is a lively addition to my reef tank. It swims boldly and interacts with other fish, which is rare for blennies. I’ve had it for three months and it’s still active and colorful. Just be careful not to handle it too closely.
Molly Piper –
This blenny is much more outgoing than I expected. It doesn’t hide and often swims near the surface. The coloration is striking, and it seems to enjoy being near the glass. No bites so far, which is a relief.
Jasmine Black –
Great personality for a blenny. It’s active and curious, and it seems to like the open areas of the tank. A bit shy at first, but quickly became bold. I’m happy with the purchase.
