   Though the Blue Tang is a bit more difficult to keep than some of the other surgeonfish, its beauty makes it a wonderful marine aquarium addition!

   This Blue Tang shown here, also known as the Caribbean Blue Tang or Atlantic Blue Tang, looks like it is changing from the juvenile to the adult coloration. Juveniles are mostly yellow with blue fin edges. Sometimes in transition, they will develop a blue body with yellow fin edges. The caudal spine is always yellow, even though this picture does not show it.

  This tang is a bit more difficult to keep than some of the other tangs. Close attention must be given to its diet and to maintaining good water quality.

I have the Atlantic Blue Tang, have had since a baby. He is starting to turn blue. I love him. I also have a Sailfin and Blonde Naso tang in the same tank. They get along so well.

I have had a juvenile for 2 months (3 inches). After the first week when the Yellow Tang tried relentlessly to kill him, the Atlantic Blue has now settled in very well. I have a 180 gallon reef with rockwork that allowed the Atlantic Blue to completly disappear and hide. Now he swims freely with the Yellow tang and all other fishes.

Have just purchased Atlantic Blue Tang and I love him, he has settled in well and feeding at present mainly on spurulina, nori and seems to be accepting cyclop-eeze not interested in pellet food yet. He is an adult fish and gets on with all the other fish.
