About a week ago, my nephew was visiting my place and was quite excited to see a little frog in my yard. He caught it, looked at it, was very interested, and was quite upset to release it again. My sister later regretted making him release it, as he was showing a lot of natural curiosity about it.

I promised her that if I saw another, I would catch it. Well my dog found it, (didn't hurt it, but would have). So now I've got him and still know very little.

I suspect he's a chorus frog given what I can see as far as native species go.
Looking for basic requirements. Obviously
temperature -- he's a local so I imagine minimal heating cooling required, but any 'preferred range'?
Humidity --- obviously I have to worry about desiccation or over moist environment (pretty dry climate, so reluctant to rely on pages quoting 'normal household moisture', but certainy don't want to over do it.
Food ---what should he feed? I doubt I can buy 'Purina Frog Chow' at my local pet store . I read some reports of crickets being fed, but I know there are also some dangers associated. Would prefer as SIMPLE as possible (ie something my 8 year old nephew can manage, and not set free over my sister's house)
Common medical complaints?
I imagine minimal direct handling is preferred. Any common parasites in a wild caught guy like this?


P.S. the local wetland which is likely this guy's home is (a) a ways away, (b) being drained at the moment, so his lifespan in the wild (even if not being eaten by my dog) is limited.
