      Aquarium Care: Provide plenty of live rock where it hunts for food. This species has Venomous fangs that it will use if attacked. Normally the fish can e found swimming or hovering in the water column, and doesn't bother tankmates unless another blenny. They are sometimes bothered by other aggressive fish, and if the Forktail Fang Blenny makes it inside a predators mouth, then it will bite it and be spit out.
