I have a 110 gallon heavily planted tank that I set up a few weeks ago. I just noticed a white worm on one of my plants, inching his way up to my driftwood. I took him out but I'm worried. I'm new to plants and know that snails are normal to get, but what about worms? Is that a bad sign? Anything I should do? I didn't see anymore. Please help......I'm kinda grossed.
