I think this is a rainbow millepora but can't remember. The mother colony has propagated itself in many new locales in the tank. I've not had another SPS do this. Its a brownish dark green color.

Picture is pretty hard to make out. However, the information about it self propagating around the tank, leads me to make a guess of some type of Poccillopora.

Most defenitly porcillapora. I would get it out of the tank asap. I've seen that species have polyp bailout is multiple tanks. Everywhere the polyps bail out to, you'll grow a new colony. Worst case I've seen was the entire tank was taken over by it. It took less than a month for the polyps to seed the entire tank, down hill from there.
