I think he is abnormally large

Fudge just keeps growing. I actually think he is visibly bigger than yesterday. Not even trying to boast or anyth I am just genuinely shocked. He will be 5 months old in abt a week and is about 50g. I don't know how old he has to be before I can tell if he is a boy or a girl. If anyone is wondering I have been feeding a custom mix of Pangea watermelon, Pangea growth & breeding, banana, vit d, and reptical (measured by gram weight dimensional analysis to make sure the nutrient proportions are safe)
