Roughly just over a year ago I set up my marine tank. One of my first fish was a tiny Regal tang. Over the months I noticed his colouring seemed to fade from his belly and the blue became extremly dark. I thought he was ill and bleached. Anyhow, he's now very large and territorial. His white belly is becoming yellow and the black marking across his body is slightly different from other Regal tangs.
I found a different and apparantly very rare type of Hippo tang (African yellow belly hippo tang) while I was searching on the net. Has anybody heard of them?
I'll post a picture if he'll stay still long enough!
