I got him for $40 at a reptile store at the mall. They know nothing of his history. He was a jouvenile, but no age or other info. Morphs weren't really much of a thing back then in my experience and I didn't have the internet for research. He looked more "normal" when he was young. I will say though over the last 10 years he's faded quite a bit. Gotten more silvery gray than brown on his sides. I never had any interest in breeding or anything, so he was always just a pet.
Based on what y'all are saying and just cause it makes sense, I'll keep him on his 7 day medium rat schedule. It's working for him. I will get a monthly weight on him now though. Just to monitor.
I appreciate the responses all. Thanks.
