[idcouple]

Ok so some of you might have read are other posts but figured would post on here. Our beardie won't eat too much the pet store we got him from said they fed him 3 adult crickets a day ******s* but now he won't eat much at all when we first got him he would eat maybe 2 little crickets then be done then he went to not eating the next day. We then got some help to make him better and more active and got him some wax worms he eat 3 waxworms the first day and 4 yesterday but won't eat any today. We have used a droper to put some baby formula squash on his nose to make him eat something and also a formula from petsmart that is supposed to increase appetite and energy. We are at a loss everyone says he is supposed to eat more but he won't any ideas on how to make him eat more or what is wrong? we have had him/her since last thursday.. :?:
