Friend or Foe?

I caught this while cleaning my tank tonight and am trying to determine if is is a good or bad hitchhiker. It is about 2 inches long and has multiple star shaped appendages on its head. The body is brown striped and covered in soft spikes. I think it is some type of cucumber and and concerned it could be toxic if it dies in my tank.

looks like a type of sea cucumber it would be toxic if it died (almost all of them are). I dont like the idea of having a one in my tank for that reason. personally i wouldnt keep it, but its up to you.

Thanks, I took it out of my main tank and put it in a small tank with other "non-reef" stuff.
