The Tail Spot Blenny is usually found in shallow reef rubble, grazing on the Live Rock for small zooplankton and algae. It should not be housed in the aquarium with other conspecific or different Blennies. Otherwise it is nonaggressive towards other fish and will do best in a mature tank with plenty of live rock. Its diet can be supplemented with algae based prepared foods, frozen, flake or pelleted. The Tail Spot Blenny's defining feature is the dark spot at the base of its tail. A black and yellow band runs below each eye, aiding them in blending into their surroundings. They are a smaller blenny with very large eyes, and small mouth giving these fish a very comical look. Generally found amid crevices and rocks on the bottom of its environment, the Tail Spot Blenny needs a tank of at least 10 gallons with plenty of live rock for grazing, perching and hiding. They should not be housed with aggressive species that may intimidate these fish into hiding. Maximum Size: The Tail Spot Blenny Grows up to 3.5 inches.
