Overview
The Mozambique fangblenny is an outgoing fang blenny that spends its day in plain view. It is easy to keep and suits a saltwater reef tank.
Did you know
A predator that swallows a Mozambique fangblenny gets a venomous nip on the inside of its mouth. It promptly spits the blenny back out, usually none the worse for the trip.
Caring for the Mozambique fangblenny
Give the Mozambique fangblenny 29 gal (110 L) or more, with a lid, since it can jump. Unlike most blennies, it hovers in open water near the rock rather than sitting on it.
Hold the water at 72 to 79°F (22 to 26°C) and a pH of 8.1 to 8.4. Feed small meaty foods a few times a day.
The Mozambique fangblenny is curious and rarely bothers tank mates. Keep it singly or as a pair, and it settles into almost any peaceful community. It does not touch corals or invertebrates. Breeding it takes some experience.
Good to know
Meiacanthus mossambicus is a fang blenny in the family Blenniidae. Its lower jaw carries grooved, venomous fangs that it uses only in defense. The body is a warm golden yellow with a dusky wash along the nape. A lyre-shaped tail is why the trade also calls it the harptail blenny.
In the wild
The Mozambique fangblenny comes from coastal reefs of the western Indian Ocean along East Africa. It ranges from Mozambique north to Kenya and out to the Comoros and Madagascar.
