had to pry off my chocolate chip from my red sea star (who sadly didn't survive and it ended up eating itself... I think). And I am pretty sure that it was the culprit of my blue linkia losing an arm (and later dying) :cry:... it's now in a tank by itself, I don't want it going after my last remaining 3 stars... so if you have any other starfish in the tank that you are particularly attached to, be careful!!
