I do
I have a Regal and Goldflake in a 340 and neither mess with zoos. I have seen the Regal occasionally nip at my Duncan, but it has been almost 2 years and the Duncan has quadrupled in size (or more). He just makes the duncan go in for an hour or so, which is annoying. The one rule of thumb about angels in the reef is that there is no rule of thumb. He could just wake up one morning and decide he is going to eat all of my LPS. I'm ok with that though, he is awesome. I doubt he'll ever touch the SPS. What size tank is he in?
BTW i feed 11 times a day, so my guy rarely gets bored enough to start "nipping."
