Pencil sea urchin
When I first acquired my salt water tank, I went to LFS and started to buy my clean up crew. One of the things suggested (and given)to me was a pencil sea urchin.
I've been doing some research and what I can find says that they are not reef safe. Does anyone have any experience/advice on this?
I have some corals now, and would hate to have them eaten.
