What kind of Tang is this?

[DerekG4]

Had a Tang come in where I work. It came in as a Chocolate tang but it’s definitely not a Chocolate Tang. Based on its looks I know it’s definitely an Acanthurus of some kind but not entirely sure what species.

If possible, along with the ID can someone post some quick stats about them? Such as their size, growth rate, aggression (if any), etcetera.

After some googling, I really feel like it might be an A. Bariene but my boss says it’s an A. Nigricauda. I’m not entirely sure which it could be, but I have a slight hunch it’s a Bariene.

You guys can close this topic now. I’m 99.99% sure it’s a Bariene. It has the same exact markings

Based on this image above, it looks exactly the same to me. It has the same orange line by the gills, the orangeish dorsal fins with a blue line across the fins, right below where it starts, same white and black coloration on the tail blade, same colored tail, white lips and the orange around the eyes. In this picture I’ve posted it hardly looks alike but now (I bought it, I couldn’t help myself) that I look at it in the bag, it looks the same to me

In the picture one would think it does look like this but I almost know for a fact now it’s not this.
