Soo i have a planted bichir tank i use dirt but i baked it twice before using it to get all the parasites out. Then after a few months ive been noticing thread like white worms in my tanks. They swim in a snake like manner, and ive tried looking it up but didnt find anything. Could you guys help to ID this. And if this is a parasite that could potentially harm my fish or me? Thank you!
Heres a gif of the worm.
