I left my magnetic scrubber (not sure what other people call it) in my tank overnight (which I don't normally do) and today when I went to move it there were suddenly tonnes of white worms!!
I checked the scrubber closer and could see more of them hiding under it, so I'm not sure if they were breeding under there or if they were already in my tank and simply grouped together there.
I think they're detritus worms but I'm not 100% so I want to see other people's thoughts.
If they are/aren't what should I do about it? Are they harmful or just part of the ecosystem?
Thanks in advance!
