Ok, just got back today from Cozumel and I went SNUBA while I was there. Now I saw Alt. Blue Tangs, but there was another tang I saw, it was the same shape as the Blue. This tang was pale in color that faded to a red on the top fin and faded to blue on the bottom fin. It had a white band in the section between the body and the tail (about where their claw is) and had a yellow tail. What kinda tang was it?
