I have a 180 gallon reef tank and it is becoming overrun by asternia starfish. After doing some research, it seems like my only option is a Harlequin shrimp. My issue is, I have other numerous starfish in my tank that I don't wish to part with. There is about 500lbs of live rock in the system and there is no way to get the other starfish out anyway. Any suggestions on how to get rid of these lil buggers?
