Okay this is going to sound like a dumb question but how on earth is it possible for my tank to be invaded by pocillpora babies everywhere. I mean I've heard of other people having this same thing happen but I don't understand it. Is it some sort of asexual reproduction? Its certainly nothing I did. I have one colony that sort of dies off at the very bottom as it grows bigger but I have never have places frags anywhere in the tank. Yet all over the tank I have little pocillpora's growing. Input from others is greatly appreciated.
