What Type/Gender is My Little Guy?

[YourSoJelly]

*tentative* Gray Tree Frog (Hyla versicolor). I don't live in the US so I can't be sure. The little guy looks too young to sex. However, with frogs, males tend to be smaller than females, croak, and develop nuptial pads by their thumbs. Females are generally larger, and are silent.

Thank you! He isn't a Gray Tree Frog, he doesn't look like any of the pictures.
