I went through the process of adding live rock to my aquarium. I have three powerheads running which produce a medium water flow. I'm ready to start adding items to the aquarium such as coral, polyps, etc. I went to my lfs
and picked out some kind of polyp. It's a small rubbery looking thing with about 5 arms sticking. Anyway, when I put the polyp on top of the live rock, the waterflow literally took the polyp and knocked it off the rock. It then started rolling on the floor of the aquarium. No matter what I did, the polyp would not stand still. Do these things eventually latch on to something? Maybe it doesn't like waterflow at all?
