Amy Parsons –
Added the Grammistes Blenny to my 30-gallon reef tank. It’s active and curious, and has not shown aggression toward other fish. Feeds well on small crustaceans and is easy to spot in the rockwork. Good for intermediate reef keepers.

The blenny is lively and fits well in my tank. I noticed it defends its space near the substrate, but it doesn’t harm others. Needs a stable environment and regular feeding. Works well with my clownfish and gobies.

Purchased the size S blenny and it has grown steadily since arrival. It’s active and stays near the lower rock areas. No issues with compatibility or health. A good addition to a 24-gallon tank.
