I just recently looked over at my hissers and there were oodles of nymphs running around! I tried to not freak out so I cleaned out their cage and refilled it with fresh food and water. There are plenty of places for them to hide. Anything else I need to do? I put a few napkins in the water dish so the nymphs wouldn't drown. Is vaseline what I should use to make sure they don't climb? They are really cool!
