That's definitely a Cranwelli. As for gender, probably a little young to tell. The squeaking you are all hearing is probably them trying to dig but rubbing against the glass on the terrarium. When the males do call, you won't mistake it, it's a bit loud and kind of strange. I would recommend listening to some YouTube clips. Every once in a while my frogs will chirp or bark at me if they think I am bothering them too much during a tank cleaning.

And congrats on your frog
