Found a tree frog?

Perhaps: Squirrel Treefrog - North Carolina

I'd release it back into the wild if I were you. It wasn't in any danger (though if the hot-tub doesn't have grills small enough to prevent little frogs from being sucked into the intake area, encourage the owner to remedy this), and you aren't set up to house it long term.

If you are interested in getting a frog, take a look at the many care articles on this site to see what's involved. Frog Forum - Gray Tree Frog Care and Breeding details gray treefrog care, and the basic care requirements will be applicable to other north american natives if they've caught your fancy. Do plenty of research before getting a frog, and have a suitable habitat ready to go, and ask all the questions you can think of here.

Brian is right. If you are not ready to take on the responsibility, which can be lots, releasing it is best for it's welfare.
