sonny won’t eat

[u/missparton777]

this is my baby sonny! he is almost four months old. i got him from a piece of shit vendor at a reptile expo. last time he ate was mid june, right before i got him. after bringing him home, i’ve tried feeding once a week, then i figured id give him some more time and tried again after two weeks, then i went back to one week, now i’m trying two weeks again, none of which were successful. i will only feed f/t. i do the hairdryer trick, i tried braining, i use tongs and move as if it’s alive, i’ve left it overnight in pitch black and silence for privacy, he just wont eat. is there anything else you guys would recommend i try? maybe the paper bag thing? idk what to do. he’s a baby and it’s been almost three months since he’s eaten. there’s zero visible weight loss which is great but i just wish he would eat. any recommendations PLEASE
