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.
The diet of the Tail Spot Blenny should include vegetable matter, including frozen and dried foods containing marine and blue-green algae. It will also feed on (and help control) algae growing in the aquarium.
