Which Heniochus are these?

[jonnydalejunior]

I would like some help figuring out which Heniochus these might be.
Acuminatus or Diphreutes.

i forget the name but these appear to be the ones that are NOT reefs safe.

I am by NO means an expert on this - just passing along what I have read somewhere on the internet. Please someone correct me if I'm wrong. I would hate to spread bad information.

The tell tale difference between the two is in the black/white coloring on the anal fin. The fin on the diphreutes (somewhat reef safe) are 50/50 black and white while the split is more like 60/40 or 70/30 for the acuminatus (not very reef safe).
It looks to me like the split is 50/50 on this guy.

Looks like an H. acuminatus to me.
