Mark, Paul has a good sugestion by getting one from another reef tank were it has behaved around sps.I have a coral beauty in my reef which I bought from Pete and it has never nibled at anything but algae.If you look back at some of the tanks of the month some of them have had lrg angels in them with tons of SPS in them.I have a Queen Angel ,Macoulosus Angel,passer Angel and a Emperror Angel as well ,but not with corals in fish only systems.I love angels to as they have lots of personality and are very hardy if you get a good one.I am thinking of adding a very large Majestic if I can find one.What angels were you thinking of for your new reef tank?
