Hey these worms come out and crawl around the glass sometimes. I am just wondering what they are and if they are harmful in any way.
They are in my Q-tank

TKOS said:They are generally only visible when there numbers get really high. That is a sign of over feeding in the tank (too much left over food at the bottom). A good gravel vacuuming will keep their numbers very low.
