i was looking at mytank this morning and i noticed a few stringlike worms squirming on the back and front glass. They are really skinny but can be up to 2'' long. They tend to hang out in the dirty part of the glass. At first i just though they were like a scratch on the glass until i saw it moved! Any idea what they are? They look like nematodes though...
