Thanks for the insight! I dunno, I may try as springtails. My exoterra viv will have a watery area near door so they bprolly wouldn't escape. Would love to do pill bugs or rollie polys but itv may be hard to find them right now. I love in louisiana and we usually have tons. If I find some, how many do y'all think I would need and how do I make sure they're frog safe and clean ?
