I was enjoying my 75gl tank last night just watching the fish and snails and crabs working away when I noticed someting on a piece of live rock! This rock has been in this tank for three plus years and as I looked closer with a red light and a magnifying glass there was a tentical coming out of a hole in the rock! I thought it was a worm, but it never came all the way out. It was about a MM around and would come out about 3/4 to 1 inch and looked like it was eating debry off the rock I tried to get a picture of it but my Impieral Angel is a camera hog.. what could this worm looking thing be? I noticed some smaller ones coming out of the same rock ( an old piece of coral ) but no other rocks seemed to have them.
Thanks guys you have really helped me in the past, I just don't want undesirable creatures in the tank!
