When is a froglet no longer a froglet?

[dragonfrog]

I have 3 D. Azureus and 2 D. Tincs (Patricias) and they are about 2 months as froglets. They are in shoe boxes (seperate) and I am wondering when I can put them in their vivs?

I really dont have much experience, but IMO I would say when you are comfortable that they look healthy, strong, active, and big enough to not get eaten of fall into some sort of crevice in your viv. I think those would be the most important requirments for graduation.
