capt, get a cbb, kleins was in my tank for 1 day and he nipped every single one of my corals, out he went luckly i was able to catch him. CBB works amazing, i have a video of mine eating aiptasia he cleaned up my tank in 1 month from over 1000+ aiptasia. by the way i have tried everything before, the CBB hands down is amazing and a beautiful fish. I got mine from liveaquaria. Instantly i put him in the tank he started eating aiptasia, now he eats frozen mysis
