I've read so mant responces to WTF questions, lets see if I get it right LOL
1. a 10 gallon should be fine for now. Once the lil bugger reaches about 2 inches you should look into upgrading to at least a 20 gallon.
2. bed a beast is perfect!
3. day temps 78-80, night 72-76... humidity 40-60%
4. pinhead crickets are great for the size you are looking into getting. Food size length equales froggies head width. you can also mix it up with the occational wax worm, meal worm, moths, flies... and soft bodies buggie. But don't offer wax or meal worms too often because they are high in fat. Make them a treat, maybe 2 or 3 a month. NO PINKIES! Stick with insects. Pinkies aren't good for your froggie because of the build-up of the whatcha-call-its (someone remind me of the word) behind the eyes and can cause blindness over time. You also risk ending up with a fat froggie!
Hmm... did I cover it all folks?
