:yes: Agree with stuckinfla about the aptasia eating shrimp. I bought a hella lot of pepprements and they only ate the tiny tiny aptasia, and I had to kalk all my aptasia, which wasn't too bad, but kinda time consuming. I would kalk your bigger aptasia tonight, and then get the shrimp tomarrow or whatever, so you've killed the big ones at least. Good luck, I've been there, so just give a shout if what you do isn't workin, or you need to be guided through the kalk process. Oh, and did you know there is a kind of nudibranch that exclusivly feeds on aptasia, and keeps the new ones under control. I've seen them on the net, and they eat the babie aptasia as well as the huge ones. I would do that as well. They are like $30 I think to get one, and then if you want more than one, to breed them which is kinda unique, you put them in a dark cabinet in thier own dish in saltwater for a while, and then it either breeds or lay eggs, and then you have a bunch of them. Anyways, kinda a funny nudi, but I've heard on the net, and from friends, theres nothing better than that nudi for aptasia. good luck and let us know if you need more help. Good luck, ali
