Tail Spot Blenny
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.

Easy to care for and adds a fun, lively look to the tank. The fish is active and helps keep algae under control. I love how it blends into the rocks and looks like it’s always watching the scene.

Great addition to a small marine tank. It’s peaceful and doesn’t stress other fish. Feeds well on algae and the black and yellow markings are very distinctive.
