Caribbean Blue Tang
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 foods.

The Blue Tang is stunning in the tank. It grows quickly and shows vibrant coloration after a few months. I have a 200-gallon tank and it’s peaceful with my clownfish and gobies. Just make sure not to keep it with other tangs or surgeonfish.

Beautiful fish with a dynamic color change over time. It’s active and needs a large tank. I noticed it’s more aggressive with smaller tangs, so I kept it alone. Feeding it marine-based foods daily keeps it healthy.

The fish looks amazing in my aquarium. The horizontal blue markings are very striking when it’s mature. I’ve had it for six months and it’s still active and well-fed. Only recommend for experienced saltwater keepers with large tanks.
