I have a green montipora cap that has some type of pest embedded in it. There are three or four different spots. I pulled the coral out about three months ago and glued the spots with super glue. That took care of them but know they are back. It looks like they are at the same spots. It looks like small antennas sticking out of the holes. If I try to touch them they retract. It doesn't look like it is causing the coral much damage but the coral is irritated. The coral puts slime out every couple days. I can't get a picutre, the coral sits at the back of tank. Not sure what they are any suggestions
