Nope, that is not sauvagii the frog looks like sauvagii in second and third pic, but last pic clearly shows it is not, sauvagii dont have any orange color anywhere. I would like to see clear shot that would show belly and legs stretched, but from what i see here it looks like phyllomedusa vaillanti or white lined leaf monkey frog. It also smaller then sauvagii should be.

One way or another it is too late for him now if you would want to get another we sure can help you set up everything for him.
