where did you buy him from?
what size tank is he in?
how is it decorated?
what is the temperature?
what type of baby food do you offer?
what size crickets do you offer?
are they too big?
are you misting him daily?
are you counting the crickets to make sure he isnt eating?
are you putting so much baby food in that you cant tell if he has eaten?
2 weeks sounds like an awfully long time for him to go without eating. i think he has probably eaten something.
has he lost a significant amount of weight?
have you tried weighing him weekly to see if he is gaining, losing, or keeping the same weight?
was he wild caught? is it possible that he has parasites? or is he guaranteed captive bred.
