The Forktail Blenny has been a great addition to my 120-liter reef tank. It’s active and colorful, and it doesn’t seem to stress other fish. Easy to care for and adapts quickly to the tank conditions.

I’ve had this blenny for three months now. It’s very hardy and stays in the same spot near the rocks. The color is bright and it’s a nice visual element in the tank.

Perfect for a small reef setup. It’s not aggressive and doesn’t require much space. I appreciate how it blends well with the live rock and coral.
