I am interested in an urchin I saw down at my lfs, it is about half the size of a golf ball. The guy just said it was a "pink one." I really like it, and I hope it will be ok to put it in with my anemones. (two btas) I could always put it in my copepod tank, but I would rather have this beutiful ceature in my true tank. Is this totally out of the question? I dont have coral, which I am aware wont work. Any suggestions?
