Are Saddleback Butterflyfish Aggressive B/Fs

For clarity, I'm referring to Chaetodon ephippium. I recently switched from a 90 gallon mixed reef to a 180 gallon FOWLR. I'm looking to add some butterflies and will be adding a Pyramid Butterfly as soon as the store gets in some good ones.

My only real experience with butterflies has been Copperbands, so I know some can be difficult. My LFS has had a small (around 2") Saddleback for a while now, so I assume it's should be eating since it's been there at less a month. I would have them feed it before taking it home.

I've read that butterflies can be aggressive to similar looking butterflies and both the pyramid and saddleback are white bodied fish. Are they typically aggressive towards other butterflies?

I'd like to add a few others in the future as well. So, if these guys are too aggressive I'll skip him.

Well he looked too nice to pass up, plus he was eating pellets with gusto. I think I'm passing on the pyramid, since they do look somewhat similar. I did pickup a larger latticed butterfly, too. Both were the same price as a single pyramid locally. They both swim near each other, so aggression doesn't seem to be an issue between them.

Nice, pics of the new additions?

Terrible photos as they were screen shots from a video I took of them. But, you can get the idea of size. You can see the remnants of the reef on the bottom.
