Try a peppermint shrimp, worked for me and I had tons. I actually wanted them because I don't have a reef and I thought they looked cool. My peppermint shrimp cleaned up three or four dozen, all sizes, in less than two weeks. Ask yourself, do I really want to be injecting hot water or "juice" into my tank when I can add a ten dollar shrimp?
Make sure it is a peppermint because I heard camel shrimp look similar and won't eat aiptasia. And peppermints are tough and should be able to elude a CBS, if not it's only ten dollars. I saw a picture on here the other day of a dimond goby with a peppermint shrimp hanging out of his mouth so I guess they taste good!
