The discriptions usually pertain to their size (length) and not their age. A neonate usually goes to a juvi in 1 year. The juvi to subadult stage normally 1 1/2 yr. But can be very subjective to the feeding response and how much food they get. So these are approximations. Bluerosy
:Sorry, I've looked but can't find this info. anywhere. What are the age ranges for neonate, juvenile, subadult and adult rosies?
