Hey everyone

I have a tiger legged monkey tree frog. I have a nano exo terra tank. I have two live plants and two branches for him to climb on. I have a couple of questions I have read they require low humidity so I keep it around 40% how often should i mist the tank?? Also I have crickets roaming freely in the tank about 3 at a time is that correct or should i put them in a bowl. I also have a shallow water bowl for him to go in and i have a UVB light in the tank. He hides during the day and I have the timer on the light on a 12 hour cycle on and off. I never see him come active or eat. I just got him a week ago?? Am i doing everything right? How many guys can I put in that tank too ??
Thanks Robert
