Should I be worried about aiptasia in my tank if I don't plan on having corals? I think my starfish is eating them and spreading them. Because I see him on a spot where one was and then he moves and it's gone and I don't know if he's getting it all or not and if he's not then he's spreading it. I think I've got like 10 now. Don't even know where they came from. I haven't bought any new live rock in like a year. Guess it was always there and just never saw it or it didn't spread? I don't know how to actually get rid of them. I heard about people using things like aiptasia x and they thought they were all gone then all the sudden they had triple the amount they had before. Should I just get like 10 peppermint shrimp and see if they can take care of it? Or if my starfish is eating them do you think he is getting the whole thing just not getting them fast enough before they spread?
