The Orange Spotted Blenny will want to eat microalgae growing fresh within the tank. A diet providing marine and blue-green algae (Spirulina) will help the Orange Spotted Blenny thrive, along with other vegetable matter including frozen and dried foods for herbivores. Do not confuse him with the Orange spotted goby.
This is my favorite blenny! He has been fun to watch and has a great personality...almost clown-like. When I get the camera out to shoot tank pictures, this is the ham of the tank....always posing and looking great!
