Last night I was looking at the tank in the dark when I noticed a tube like thing come out of a hole in my live rock. It looked like a tube or tentacle of some sort. The hole in LR is no larger then the tip of a ball point pen, the tube would extend or stretch to a length of about 1.5" inch from the hole and was about the same diameter, it was white or clear and very smooth in appearence. (Tank was dark) I never saw anything else of the creature other then the tube and I am not sure there is even room for anything in there since I didn't know there was a hole in the rock in the first place. I wouldn't be able to get a picture, and when the lights came on the tube went back into the hole??? Any ideas what it could be.
