As I told ya'll before I have an Aiptasia problem. I am going thru a bottle of Aiptasia X in a little over a month, @ $20.00 a bottle. My LFS sells (sp) Kline Butterfly fish that he says will kill all the Aiptasia in my tank, I told ya'll this in my last post on this problem. The opinions I got here about my problem, was to get a few Pepperment shrimp and to let them deal with this. Well, my LFS can't get any Pepperment Shrimp, he orders them for me, and then they don't come in. Sooooo I got one of the Kline Butterfly fish. I have been resiting getting the fish because I just didn't want another fish in my tank, the shrimp, if they died I could just feed them to my Rose Ann., anyway he told me the fish wouldn't hurt my Zoas and polys, so I broke down and bought the fish because I am tired of dealing with this Aipasia.
