Easy to care for and very peaceful. I’ve had it in my 24-gallon tank for three months and it hasn’t shown any aggression. It’s a great addition to a reef setup.

The blenny is active but not disruptive. It stays near the rockwork and doesn’t bother the corals. Perfect for a small reef tank.

First time keeping a blenny and it’s been a joy. It’s calm, doesn’t hide, and adapts well to the tank environment. Highly recommend for beginners.
