So last night I was looking in the DT after lights out and I seen 2 worms one in a bottom rock and the other in a rock that my big mushrooms are on at the top of the tank. I tried to get a pic but both are very shy and as soon as I put light to them they move out of sight! The one is about 3 inches long and really thin the other is a little longer gray to brown with dark bands. Almost look like a skinny dew worm? I've been looking all day for these on different sights and came up with nothing. They don't seem to be bothering anything (YET)! Any ideas?
