So I bought a red knobby starfish several months ago (I think that's what it is anyways). I was told it was reef safe, he said he has 2 in his reef aquarium and they never hurt the corals. Well I bought a frogspawn several weeks back and within an hour the star had wrapped itself around the base of the frogspawn and stayed there for hours, I would say at least 10 because it was still there when I woke up the next morning. The frogspawn died less than a week later. I don't know if it was coincidence or if it was murdered. I have had a little thing of zoas (around 10 polyps) for a little longer than the starfish and he never touched them. They always did fine, not much growth but they were surviving and looking good. Well last week the star sat on them for a good 5-6 hours and now they don't open at all and look as if they're dead or dying. It's frustrating. I will post of pic of the star when I get home so I can have a positive id and opinions on what might have happened.
