I bought my harlequin to remove asterinas. I tried manual removal, but they reproduce so fast that it seemed impossible to remove them all. I had hundreds, if not thousands of them in my tank. They were completely gone in about 1 week after I bought my harlequin. One of the best investments I ever made! I lost a lot of zoa frags and colonies to asterinas before I realized that they were causing the problem.
I would definitely go with a harlequin. They are super easy, and hardy for shrimp. After it wipes out your asterina problem just buy a few chocolate chip stars, chop them up, keep them in the sump to heal, and give the shrimp a leg or two every week.
Good luck!
