I have 2 things that I noticed on my rock. I did a bit of a cleanup job and moved some rock around in order to make some of my equipment more accessible. When I did I found something that looked like a coral that I have seen at the LFS. I can't find any pics that look like it and my camera will not focus on it what I try to take a picture. I know I am being vague. One looks like a tube and it has a base. It has something sticking out that is very thin like a hair. When I shine light on it it eventually retracts the hair like thing. I have not introduced anything new into the tank that it could have came from.
