Hi Paul B it seems like you are some kind of CBB expert, at least according to Hal3134

I'm considering one b/c first of all they're gorgeous but also for aiptasia control. I have a fairly new tank though (since mid March) and want to make sure I'm ready to give him the best chance. I have a few easy soft corals and some zoas - if I feed a CBB right can I be reasonably sure he won't eat my corals? I have just used aiptasia x on the ones I can see and the guy at the LFS told me to get a CBB plus a filefish to clean up the rest of the aiptasia. I'd prefer to just get a CBB and a yellow tang for algae control (but also b/c I love them). I thought if I added them together that would be best to avoid any aggression issues. I also have 3 yellow tail damsels, 4 clowns, a marine betta, a royal gramma, a long spine black urchin, a pincushion urchin, a sand sifting star, 2 hermit crabs, a bunch of trochus snails and 3 sand sifting snails. It's a 90G tank. I'd appreciate your input re the CBB, I'm mostly just nervous re a CBB nipping at corals. I know peppermint shrimp are also a good option but I've seen the betta go for snails so I suspect he would want to eat the shrimp...
