Hey guys, I recently received a CB baby ball python around late February. He shed the day I got him and hasnt since nor has he eaten any of the frozen pinkies I have tried to offer him since. Now before I even got the ball I researched them and how to properly set up a enclosure, temps, etc(mostly lurking here). I also heard they are picky eaters, but mine just refuses to take food. The snake itself doesnt appear sickly at all, as he is lively and seems to love being handled. At first I thought it normal as I read during the colder months some males go without eating, but now he is starting to appear to be getting thinner. I really could use some help.

My stats:
20 Gallon long
2 hides, one on warm side one on cool
Warm side has a heat matt, set to 90F. Air temp is in the 80s
Large water bowl in Middle
Cool side is in the 70s with about 55% humidty
Substrate is Aspen snake bedding.
Been offering him frozen pinkies and small furries with long tongs, shows no interest at all. Tried feeding him in his enclosure as well as outside it in a small enclosure.

I cant think of anything else but to try live, sorry for the long post. Could use some input as this is my first bp.
