I know people swear by spring tails in vivs. But I googled it and became affraid for my house plants. Especially my Titan bulbs, bananna tree, and everything else soft skinned. I wouldn't want them loose in my house!!!! Maybe the ones people use are different variety than what came up on google. I don't know. I'd rather clean poop. I also heard that bead a beast(soil) spoils and sours in viv and u have to change it. That's why I went with pots, affraid I guess. But I think don lisk uses it? Maybe ask him bout that.
