   The hardiness and ease of maintenance make the Convict Surgeonfish a good addition to an aquarium for the budding marine enthusiast!

   The Convict Surgeonfish or Convict Tang is not as striking in coloration as many of the tangs you will see and so has not become as popular. However it has proven itself to be one of the easiest tangs to keep. It will quickly adapt to its environment and is quite hardy, a great fish for the beginner.

   An adult Convict Tang can reach up to about 8 inches (20 cm). It is easily identified having a generally white body with six narrow black bars. The dorsal and caudal fin has a light yellowish-green cast.

I purchased one that the LFS marked down because they had it in a tank full of yellow tangs that were beating it up. It acclimated quickly and swims all over the place in my tank. Not aggressive at all like some other tangs can be. Grazes the rocks and eats pellets, flake, froze and veg/algae sheets no problem. I wanted a Kole Tang before finding this one and I am glad I got this guy instead. Great fish!
