Well, it has a white tail, at least it looks like it in your photo. Bristletooth for sure. So use those two tags and search away on your favorite search engine. I would second white tail tang.

I disagree, while this tang have a white tail, it is not a Ctenochaetus flavicauda due to wrong body shape, mouth shape and rounded dorsal and anal fins. It is not even a Ctenochaetus tang at all but one in the Acanthurus genus.
How big is he?

Y'all are barking up the wrong tree. It is one of the larger more unusual Acanthurus species.

Consider A. bariene or A. thompsoni. I don't have experience with either but that they get BIG.

Maybe. Which is why I suggested searching :). Below are tangs in the Acanthurus genus per your suggestion.

So now is not so big... Around 6cm but is growing faster than hepatus and also he eats continuously algae from Glass and rocks...

I already made a research but not so clear for me... Could be an hybrid? Now he is starting to change color to clrear brown...specially in the dorsal..

Does it have a dark spot at the upper base of the tail which is a tail-tail sign of A. thompsoni. Some of the Thompson Tang have dark tail while other have white tail (regional variance or sub species). It is too small right now to reliably tell I think.

No any spot visible
