I received a new frag today that I noticed had a white spot in the middle of its main body. I got looking at it closely tonight and noticed a sweeping barnacle fan coming in and out of the white spot that is on the body. I took the coral out of the tank and took a straight pin and poked it into the hole and it was like a woodpecker hole in the middle of the coral. I will watch to see if the stick pin killed it. Looks as if it has distorted the growth pattern somewhat. Never thought I would see something like that.
