Hi busytiredmom4, and welcome to the forum! (Love the username... )

Sorry, I can't help with the tree frog, I've got zip experience with them.

As for the toad, an easy, fool proof way to sex them is by waiting for them to "croak". A toad has a very distinctive call, almost like a shrill peep. My two toads never uttered a peep, until one morning (around 4:00am) I was woken up by my toad "croaking", thus telling me that it is a male. They are around 6 months old, so if yours is a male, it will start to croak, very soon!

You don't keep those two in the same tank, do you?
