Just put egg crates for their hides
A shallow dish with pebbles so that the nymphs would not drown. I personally feed my lats stag developers (chicken pellets that are high in protein), oatmeals and veggies.
If you want, harvest the egg cases so that you can separate the nymphs from the adults. And let them be. They breed fast like hell
so for me lats are the most practical and efficient feeders.
Imma post some pics of my enclo and the colony
