So far I've had Monty for two months and in that time I'm pretty sure he's gained 200 grams and right now I believe he's pushing 400.
I have to say I feel pretty lucky since he was originally being fed live. I switched him to f/t without any issues or fuss. I also switched him to f/t rats without any issues or fuss and got rid of his mites he had with little worry or stress.
He shed beautifully in one piece and his colors are very pretty. He does have some odd scales that look like scars that were there when I got him but other than that he is healthy, fat, and adorable. Here's some bad post-shed pictures. His eyes were very bright and clear after.

I also got to witness his shed when it happened and saw him drink today!
