if there are really really tiny light colored worms on the sides of your tank, does it harm the environment in any way? i know loaches eat worms, but what about cory cats?
really thin white worms that kind of inch there way across the glass?
i had those in my o tank and they didn't seem to do any harm cleaned the glass a little though
i had that in my 120g for awhile, when i took out the driftwood and put 4 AC 110s on there instead of the canister, and in about 2 weeks no worms. I figured they were breeding in the wood and the canister filter.
