I am having a little outbreak of Asterina Stars. I was thinking of getting some Harlequin Shrimp and see if that would help the problem. If anybody has tried Harlequins for Asterinas and has not had success please chime in as well as I know these kind of stars aren't their main choice. I have a Grey Head Wrasse that really doesn't bother anything. It might grab a snail once in a blue moon and just toss it across but doesn't attack anything. The stars don't seem to be bothering anything but they are becoming a little more than I would like and they are absolutely tearing up my Coraline which I love. I kinda of want to see the odds if there are any people out there doing it with any kind of shrimp at that. TIA
