These are closer in size and care to a Hyla cinera: Frog Forum - Gray Tree Frog Care and Breeding

Hyla cinerea are a little smaller and more delicate looking and don't have the freezing capabilites of a Hyla versicolor, but their range and habitats overlap so most of your questions are answered in the caresheet.

My Hyla cinerea is big enough that I feed it crickets a molt or two away from full on adult. Fruit flies are most often found where dart frogs are sold, the frogs will probably get too large to bother with them after a few months. Mine also devours earthworms like it has a grudge against them, but I would doubt this is a species wide love (earthworms are excellent food though, and worth trying).

Mine hardly bothers with the pool I gave it to soak in, so I wouldn't bother with a major water feature, but do have something they can sit in if they want to hydrate. I don't bother with an auto-mister, just hand mist every day and keep the water supply fresh. These are native North American frogs and don't live in a constant 80+% humidity in the wild.

No UV bulb for me.

I only have one of these frogs, so can't speak for territoriality first hand, but I don't believe any of our North American treefrogs are anything but relaxed when it comes to neighbours (breeding season can be an exception).

I probably wouldn't want 3 adults in anything less than a 30gallon or so, and height is way more important than floor space. Make sure your lid is secure- they can squeeze through very small cracks. Smaller than you'd think until you see them doing it.

They also have pretty decent chameleon like ability to change their skin colour- mine ranges from a bright green to a dark brown on a daily basis (see my albums). Not quite the range as a Gray Treefrog, but still pretty impressive.
