I went to the LFS today to pic up a few thing, salt, fish food and some cyclop-eeze ( which I forgot) and a bottle of Aiptasia X. The LFS man asked me if I was having a problem with Aiptasia and I told him not a problem but I had about 10 in the tank last nite that I treated with the A. X. He took me around the corner and showed me this fish (not a big fish) and told me that I needed to get one of these and that it would eat Aiptasia as fast as they would grow. Well, I figured I would check with ya'll before I buy a fish that I might not want to get. I wanted to make sure that there isn't a down side to this fish, will he eat my polyps or does it have any bad habits, do I really need the fish. Also, as always, I forgot the name of the fish,lol.
