I have a male AFT whos around a year old. We made a move about a month ago, and around the same time I switched his substrate from jungle earth to paper towels. Since the move (i dont know if it is significant or not) he hasnt eaten, at least not very much. It was colder in the house that we were at for the last month -- maybe it was too cold (but there was an undertank heater and a night light on at all times.) His bottom lip also appears to be a little red, chapped looking. Im not sure whats going on with him, and I plan on taking him to a vet, and also contacting my local reptile center, but im not sure how big of a problem this is.
Any input would be greatly appreciated.
