A few weeks ago I bought a big colony of flower pot and in the last few days the skeleton has been showing a little at the base. This worried me so I took a close look when the polyps were retracted and noticed two tube like structures in the middle. One had something in it that retracted when poked and the other seems to be empty. (It looked like some kind of worm to me, but it was to far in the tube to see.) I dipped the coral in Coral RX but that had no effect on the creature. Do you guys have any idea what this could be and do you think its responsible for my coral dying?
