Received the Bicolor Blenny in excellent condition. It’s active and curious, exploring the tank daily. The two-tone coloration is very vivid and stands out. Easy to care for and fits well in my 30-gallon reef tank. Highly recommend for new reef keepers.

This blenny has become a highlight in my tank. It’s peaceful and doesn’t bother other fish. The color pattern is stunning and it moves gracefully through the rockwork. Very happy with the purchase.

The fish arrived healthy and looks vibrant. It’s about 3 inches now and seems to be adjusting well. A bit shy at first but now it’s exploring more. Would buy again if I had a reef tank.
