My torch was my very first coral. It was growing great for the first few months then I noticed that it wouldn't extend its tentacles as long as it did before. This is how it first looked. I did notice a vermetid snail on it that I removed with no change. There was also an area on its skeleton that was growing which I thought was a new head. Tonight I was target feeding my corals reef roids and squirted a little on my torch. I noticed the growth on the side of it move almost like a clam. It closed itself and pushed out the food. This is the best picture I could get of it. Usually the torch's tentacles hang over it and you can't really see it but tonight it had them all pulled in. At this point I'm sure it's not the growth of a new head but I have no idea what it could be. Any thoughts?
