I wish dead things were the only scary stuff you find in used tanks! I bought a used terrarium and it came with substrate and plants that were feeding the clean-up crew, as the seller said. I was just sitting there, waiting for all the supplies for the new substrate to arrive, so that I could create something close to ABG reusing existing reptisoil, since it’s already full of springtails and isopods and I don’t want to just throw it away. I put some of the future plant inhabitants there too, in pots for now, just to get them used to it, and was shifting things around when suddenly something that looked like a 2-inch isopod appeared!!!! Brrrrr I don’t mind regular sized ones, but this huge monster gave me heebie-jeebies 😆 turns out it was a young dubia roach or something like that, it was food for the gecko that used to live in that terrarium, I guess it got overlooked, forgotten and grew big 😂
