Well I'm certainly no expert on Florida frogs, but it does look like a Green Tree Frog to me, based on the white stripe above his lip. Your setup looks fine for now, I'd say just go ahead and add your coconut husk substrate, maybe find something more natural to replace the styrofoam cup with, and I would definitely add more plants for your frog to hide in. English ivy and pothos are both good hardy options. Spider plants look nice, creeping jew, etc. I would tape dark paper to the sides and back (on the outside of the tank), and add a 60 watt daylight blulb w/ reflector to one side of the tank.
My pleasure

Hope it helps!
