I have worms that look like earth worms and they come out of the rock at night. If I shine a light on them they retreat back into the rock. What are these(Good/Bad)? I will see if I can get a picture of them tonight.
I know that they are not Bristle worms as I know what they look like and how they move. Here are some shots I was able to get prior to them moving back into the rock.
Thanks for the responses. It was weird seeing something like an earth worm in the tank. I have seen them in there for a while but never knew what they were cause they would run faster then they do now.
