hi, new to the hobby and bought my first ever T's about a month ago (4 gbb slings) . They accepted food almost immediately after i got them and all seems fine but three of them won't stop eating. I feed them every 2-3 days and 3 of them are as fat as the one in the first 2 pictures and 1 is not accepting food but is also a bit less fat (see pic below) they still havent molted or stopped eating except for the one. Is a month without having molted long or is it just fine?
