I would be afraid these would be predatory nudibranches. Especially coming in on a piece of coral. Them leaving the coral they came in on however, may be a sign they eat something else. At the very least, watch them like a hawk. if they are coral eaters and they lay eggs, you are going to have a hard time removing them.
You should closely inspect and dip new additions to the tank.
