Diphreutes is considered reef safe. acuminatus is not. good luck telling the difference between the 2 when they are juvies.
Yes can be hard but the Heniochus acuminatus has a longer anal fin and a different snout/mouth. H. acuminatus don't really like groups either, so you do have to try to get a good ID. They seem ok in pairs I guess but not large groups like H. Diphreutes.
