Bluespine Unicorn Tang (Naso unicornis)

The Bluespine Unicorn Tang, also known as the Unicorn Tang and Unicornfish, and is blue-green to olive in color, with a blue edge on the dorsal and anal fins. Two bright blue dots appear at the peduncle spines near the tail.

The horn of the Bluespine Unicorn Tang develops when the fish reaches a size of approximately 6 inches. It is located far back on the head and does not extend farther than the tip of the snout. It has large, permanently erect peduncle spines which can easily be tangled in a net or cause injury to the handler.

A 360 gallon or larger aquarium is necessary to provide plenty of swimming room and places to hide. It is aggressive towards its own species, but peaceful with other fish.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.
