Hi Steve, I probly keep more angles in my reef than any one else around the boards. i have a majestic adult, a french med, imperator juv, blue faced med. their in my 180 reef which houses many lps, sps, and leathers. the only coral that was nipped at was a green brain coral, my red brain coral was not touched at all, the only soft coral that gets an occasional nip is the finger coral, and the nipping dosen't bother it at all, they never nip it deep, just the outer layer. the leather looks great actually it might even be helping the finger to shed the outer skin. i have many polyp rocks that are never touched. the key is to feed well, i use an ehime auto feeder to feed a small amount of flake 3 times per day, i manually feed 1 cube of angle formula or formula 2 once a day and late at night 9pm they get a half cube of brine shrimp. i also feed either romaine lettuce which they go crazy for or green nori
which they also go crazy for once a day. so i guess my success is due to their being food in the tank every 3 hours. I do have a 200 gallon sump/ pond connected which also has an aero foamer 830 in it. my pond has a 12"deep sand bed.
