Heniochus Butterfly Questions

[cowboyswife]

Can you guys give me some info about this fish? Some websites say that they are aggressive, and others say peaceful. Some site also say that they are reef safe, and others say they arent. Do any of you have experience with this fish in a mixed reef tank? Would a 150g tank be a large enough home for one? Any tips would be greatly appreciated!

There is Heniochus Acuminatus and Heniochus Diphreutes. The Heniochus Diphreutes is supposed to be reef safe. They are very hard to tell apart.
