my friend fed him some crickets while i was gone and made sure he had water, he also turned the light on for him during the day so i dont think it was anything on his part. as for color he has gotten darker lately and you cant see his back spots as well. his spine is more pronounced than it usto be and that started a couple days after i got back. i think im going to realease him, id rather he be healthy in the wild then sick with me.....thank you for your insight.
