Hi folks. Ive got a tang in my tank that i purchased a while ago. It said it was a kole tang on description. Anyway Its been in my tank a while now and for months I ave thougt it looks different from kole tangs ive seen before. It doesnt have a yellow eye. And its brown all over with tiny little dots. Sorry for the poor picture but its the only one I could get but im not sure its a true kole. It does the same job as a kole in grazing all day. Anyone got an idea what tang it could be if its not a true kole tang.
