Sump it. It may eat zoas

[Gilbertg78228]

are there such starfishes?

[ErikH]

That eat zoas? YES. Asterinia stars will eat your zoas like crazy. I recently sumped a cowrie I caught mowing down a field of zoas. You could get a harlequin shrimp, but you would need to get a pair so they can work as a team against a large starfish.
