The Blue Caribbean Tang, also known as the Atlantic Blue Tang, Blue Tang Surgeonfish, and simply the Blue Tang, has an oval body with bold markings that change as the fish matures from juvenile to adult. A juvenile is bright yellow with two blue bands at the eyes, and additional blue markings at the fringes of the dorsal and caudal fins. When mature, the blue will become even brighter with markings running horizontally along the entire body. It may have a yellow tail.

A 180 gallon or larger aquarium is necessary to provide plenty of swimming room. It is aggressive towards other Tangs and Surgeonfish, 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.
