Heniochus diphreutes or acuminatus?

[haninja]

I find it very hard to make a decision on this one. I got some help from my local club but I’m not 100% sure which one it is.

It doesn't look like the reef safe one - it's snout is to long

i forget the other characteristics to look for without looking it up.

Had to put the pict in photoshop and magnify, but I count 8 spines behind the flag.
8 = acuminatus
7 = diphreutes ("lucky 7")

That anal fin screams diphreutes. 99.9999% sure

Sorry for the lousy pic, but this one is reef safe

Eight spines - it's H. diphreutes.

Thanks but I'm still confused: 8 spines = acuminatus or diphreutes? I got two answers...
And just to make sure, the diphreutes is reef safe?

I would say based on the rear black stripe, it's a H. diphreutes. Here is a good thread, which describes how to tell.

My bad (thanks Chiblis!): 8=diphreutes 7=acuminatus

diphreutes is the reef safe one. Have had one for almost 1 year. Trouble-free fish IME.

It's diphreutes. Just checked Scott Micheal's "Marine Fishes" and it tells how to identify.
