What am I?

The tail in the link from fishbase isn't quite right though, hence my fence sitting. Some of the pictures show a yellow or white ring on the tail, which I'm about 90% sure the fish doesn't have.

He is going to give the fish 24 more hours and then decide what to do with it. I may put up a post on his behalf tomorrow if he feels the fish's interests are best served elsewhere.
