My domino and my sea urchin seem to have made some type of relationship. The domino almost looks like he's trying to host in the spiney sea urchin. Which seems really odd to me. He backs up carefully into the spines of the urchin and the urchin just sort of pushes the domino back and forth with his spines. Is this normal? I've seen them do this several times.
