Mines is usually. Around 50 during the day. 80 too high u only want high humidity at night when sleeping sleeping around 70 rh. But try keeping it around 40-50 during the day. Mine does fine at that range. But they are all a little different. But only keep it high at night.
Depends on which u want to feed him. Like I gut load my roaches. And for crickets I just give them cricket feed. I don’t gut load the super worms. And hornworms come with their own feed. There’s lots more u can feed. But those are the ones I’m using now. Will get different one in future...
Welcome to the forum. Yes You have to cut load your feeders. And dust then too with calcium. Also give him D3 twice a month. Read up. Lots to learn. But overall easy to take care of him once u get the hang of it!
When the temp drop my Cham stopped eating. Now that it’s starting to warm up he’s eating regularly again. Maybe having him near the window is dropping his temp and slowing his metabolism. Try moving the cage to a warmer place.
