I purchased a bearded dragon from petsmart a few months ago but Petco has more decor options so while I was in there shopping I stopped and looked at the beardies. There was one juvenile dragon in the tank with the larger dragons which are kept on sand substrate. The juveniles should not be because they will eat it and it will cause impaction & death. The baby bearded dragons mouth and head was almost completely covered in sand to the point it couldn't close it's mouth all the way. It wasn't moving whatsoever and barely holding its head up. I am certain that the baby beardie didn't make it longer than two days max after that. Petco should know better. I left the store almost in tears and will not be returning. It was cruel how their reptiles were being kept.
