Hey guys, I just noticed these worms that seem to be living just above the waterline. I only noticed them because I added some water and a few got swept away. Any idea what they are and if they are a problem? I manged to get a few out and catch them on a video. https://www.youtube.com/watch?v=GvZs4MStmGg
I believe they are nematodes, roundworms, since they are so wiggly. I'm fairly certain that having some are both inevitable if you have live plants and okay. Carnivorous fish like bettas will chow down on them for a snack. If you notice a few, I'm pretty sure it's fine, but if you notice the tank is overrun, start feeding less, do larger more frequent water changes, and clean as many things as you can.
