Abigail MacDonald –
Added Smith’s Blenny to my 30-gallon reef tank. It’s active and curious, doesn’t damage corals, and fits well in the setup. Good for intermediate reef keepers who want a dynamic fish.
Madeleine Coleman –
The blenny is healthy and active. It spends time near the rockwork and seems to be adjusting well. A bit more aggressive than expected, but manageable in a larger tank.

Perfect addition to a mid-sized reef tank. It’s not overly aggressive and interacts well with other fish. Easy to spot and maintain.
