I took this picture today. It was atleast 4 inches. All wasn't visible. I am really freaking out. Is it an earthworm. I fed my catfish earthworms when i was fishing this spring. A few days ago I thought I saw small thread like worms about an inch long. I hope they are earthworms, but now I am scared to put my hand in there. lo
l
Will they hurt me? What are they?
