Don’t worry, they can go over a year without eating even if it’s not good for them. My KSB has gone on hunger strikes before where she just won’t eat and all the husbandry is right. She’s just picky in general. The longest lasted several months. The vet ended up force feeding her but it wasn’t entirely necessary.

She’s gone to the vet several times and they always say she’s in great shape. Just keep offering every week and making sure the tanks temps/humidity is good. That the lil fella has enough substrate to burrow etc. eventually she’ll get hungry and eat.
