WAIT...A...MINUTE!! You mean when I lost all but 2 of my 38 zoa colonies 2 years ago it could have been these little A Holes all along?!?! I still can't keep zoas. I thought I was fighting some mysterious water chemistry problem that wasn't showing up in multiple water tests. I thought the consensus was that Asterinas were ok. So NO?? Not really!! These are murderous bterds after all?? I have at least a couple hundred of these things now. So what's that shrimp that eats starfish? And has anyone found an economical solution to feeding said shrimp once the Asterinas are gone?
Oh, and so sorry to hear about your zoas Cody! That really sucks!! I know!
