The Bellus have always been safe for me. I have also had very good luck with Goldflake angels, with the exception of random acts of violence against only the most expensive zoas.
Currently I have a Bellus pair, Flame back pair, Venustus pair, Flame, Mutli-color, Regal, Trio of Golden and Multi-bar.
During the daytime with lights off the Goldens occasionally show up and nip at the bottoms of colonies but don't do any damage.
The multi-bar has been a great fish, but after 12+ months in the tank in 1 week it wiped out 3 small colonies of acans. I have softies, lps, and sps. And nothing gets picked on to the point of showing any marks.
