Are there any reef safe starfish?

[my2rotties]

I bought two pillow starfish a couple of months ago for my clean up crew. They were in a tank with mushrooms and softies and I was told they are safe. One was evicted to my sump over a week ago for eating my multi coloured ricordias, and is waiting to go back to the LFS (was trying to find the other pillow star).

This morning I found the other (I literally could not find him to evict him from my display) destroying my bubble coral. I bought the bubble from a canreefer and it was a pretty prime piece... now I am not too sure anymore. I don't want to take it out and stress it out anymore. It looks like a good chuck of it is gone from the skeleton though.

I have a sand sifting starfish which seems safe and two brittle starfish which I make certain to target feed since they look like they might eat a fish one day. However fish can get out of the way for the most part, corals are pretty defenseless...

Hubby wants to to bring it to the LFS and throw the starfish at them, but that's not really a solution to the problem. I was told they were safe and they were both with softies, so I guess the LFS and I both learned something more about starfish. I had asked about the pillows since I had a chocolate chip starfish that did the same thing. I didn't want a repeat but when you think about starfish I guess they would all be the same in the end any ways. I'm pretty steamed about the damage to my bubble coral and don't know if it will come back now.

If there are any reef safe starfish please let me know. I wanted them for my system since they are great cleaners and my puffer doesn't eat them.

My first instinct was to dry them out for show pieces but I will be making the drive to the city today to return to where I bought them from. It's not their fault I hate them at the moment... they deserve a chance. I am REALLY ticked off right now, not at anyone in particular, just my luck. MY bubble is looking worse now and I just brought it home last week. I am not sure how they work but it is missing a third of the bubble part and its mouth is open now. It is not wanting to inflate but the halides still have yet to go on.

A fun day in the hobby, but I still love it.
