I try to keep a nice thicker layer of leaf litter and some decent sized pieces of cork bark for the isopods to hide under. Just this morning I caught my two girls hunting their clean up crew. Occasionally I’ll give the cuc some of whatever I’m feeding my feeder insects - I put it under their cork bark so they can stay hidden as they enjoy some fresh veggies. Every now and then I’ll find an escapee isopod strolling down the hall. I’ve determined that some came out when the leaf litter had become sparse in one of my chameleon enclosures as once I refilled it, they stayed put. Others may come from my leopard gecko tanks if things get too dry for them. I took
@jamest0o0 suggestion a while back and bought giant canyon from him. Not sure how many generations it’s been, but their offspring are in all of my chameleon enclosures and leopard gecko tanks and I keep a small colony of them for future use.
