I already have isopods and springtails coliving with them but this is the first time I'm seeing these. Since they're crawling up from underneath where I usually leave food I can only guess they're here for veg, just want to make sure it's not some obvious parasite I'm not aware of 😬
Edit: https://www.reddit.com/r/terrariums/s/Lh7nhkJTB3 I did some searching because I was rapidly getting more and more panicked, however, we might be good, saw this and many other posts on a terrarium sub about what looks to be exactly the same worm, including the way they cluster up. They appear in overly moist places, which I have to confess I am pretty heavy handed with watering, but aren't immediately harmful I think??
Edit 2: after looking at worms for far longer than I would prefer, I've rounded it down to most likely be grindal worms, conditions they thrive in, the way they cluster, their symi transparent and segmented look all seem to line up. Grindal worms are harmless and are cousins of springtails by the role they play, and many aquarium people cultivate them for fish food.
