Is this a Heniochus diphreutes? or acuminatus?

[drgmeh]

I found this at Petco, not the best place to buy fish but he is hugh, hes about 5" accross. I have him in quariteen. I think hes a Heniochus diphreutes, any body know for sure? I can return him if hes not the reef safe one, I have that in writing. Of course the store didnt know a thing. I have looked all over and its confusing which is which.

I posted on reef central as well and everybody there told me diphreutes, very confusing, this is the picture they gave me of a acuminatus. "Yours has a short snout and a much rounder chest, signs of an H. diphreutes..." Im not saying anyone here is wrong just very interesting opinions.

The black-white margin on the anal fin is right through the middle of the fin on diphreutes, and is higher up with acuminatus.

I think you're all set.
