I've always had great luck with serpent stars but any of the others have always slowly withered away on me.
same for me. like many others, i tried linckia's and then fromia's... looked great for a couple days and then dead within a week or so. the common starfish from kp aquatics are the only hardy starfish (aside from serpents) that i've been able to keep alive long term. I have a lot more reefing experience since i last tried linkcia's and fromia's but i still don't dare try it again.
