Whats the best substrate to use for nymphs. I had a few probs recently i hatched a european ooth put the nymphs in a plastic tub but i saw that when they were trying to climb the tub and they fell they fell on there backs and were struggling to get to their feet. so i tried to put some kitchen roll in but they were getting under it and inside it i didnt think that was very good at all. So the only thing i could think of was the fine vermiculite i used with the ooths to keep the humidity up. It seems to work ok i just wondered what others used. And if they could give me a few ideas CHEERS!......................
