Depends on whats in your tank coral wise... If you are strictly SPS, most of them are okay. A guy I trade with on RC is an Angel specialist, hes spoken at Macna etc a few times. His advice is if you have SPS to stick with the Chaetodontoplus family and you should be okay. He's kept most of the industry available Angels and hasn't had any cause problems. However, he warns that LPS and softies, zoanthids, palys etc are all fair game and will likely be eaten.
As always though... each fish will act at its own accord. When I was asking him about one for the 300, he suggested the Scribbled or Personifier out of the ones I had picked out as potentials.
