Congratulations Corey. Welcome to the dart side. Imitators are a great dart. They're definitely little characters. As far as humidity 80-100 % is right so the higher the better. High humidity good high temps not good.

the tree fern looks great. You need a couple of neoregelias for them. They provide good sleeping spots, hideaways and egg laying sites. For additional egg laying sites add film canisters. Best of luck with them Corey.
