starfish... please help

[corcoadam]

I've posted before and no one responded so I'm going to try again...
I have had a serpent starfish for about 3 months. He's been the only organism in my aquarium beside some rock. Last weekend, I added a clownfish and a condi anemone. A couple days after that, my starfish started autotomizing his legs and he now only has one left. Why is he doing this?
Thanks for any help

It sounds like it was not acclimated properly. I have heard that when a starfish is not acclimated properly it might take a month or two to die. How did you acclimate the starfish? Is there any chance it could have gotten caught in a powerhead?
