I have about half a tub of springtails left from the bioactive vivarium for my crested gecko. I was wondering if it would be a bad idea to add them to my tortoise enclosure. I removed the pots from the spider plants and planted them straight to the substrate. I'm using cococoir and sterilised topsoil. i've been using this mix to grow tortoise food and I've had really good results. Do you think the springtails will do any harm to the enclosure? or my tortoise?
