Hello! I’m starting a vivarium and ordered some Dwarf Tropical Isopods from Josh’s Frogs along with some CUC cuisine. I put a tablet in a day after they got here and left them for a few days in their container. While sifting through it today, I found a bunch of these little white worms. It appeared they were mostly concentrated around the CUC cuisine tablet, but I’m not certain. I removed said tablet for now. The worms are roughly the same length or slightly longer than the isopods, but much thinner. I have included a picture with the worm circled. The tip of a standard butter knife is next to it for a size comparison (the worm is small, you can’t see any obvious features. They are very squirmy and would sometimes wave their head/butt around in the air when exposed). The leading candidate from my internet searches is a fungus gnat larvae. What do you think? Any reason to be concerned?
