No, he is way behind. At 9-10 months old and male I would expect your ball to be between 400-600 grams. If it were female I would expect 500-800 grams.

What size mouse are you feeding him? Pinkies? Fuzzies? Hoppers? Weanlings? Adults? Jumbos? How much do each mouse actually weigh? 90g for a 3 month old is very small and 6-7 months after that has only gotten to 169g? There is a problem. Some grow slower than others, true, but not that slow. I suspect you are feeding way too small of meals. At 169g your ball should be on rat pups or adult mice once every 5 days.
