Shame on me, I didn't even see the second part of the question.
A 10 gallon tank with be just fine for one individual, you'll want to use coco fiber or the like as a substrate. A water bowl is not needed, just mist the glass everyday. The temps need to be 80-88f during the day with a drop to about 60-68f at night.
As far as feeding items go, you can feed them crickets, flies, wax worms (in moderation), and they absolutley relish moths. Also, you can give them a mixture of honey and water or the nectar mixture you can buy for hummingbirds. I have used both methods with success.
I sure miss keeping these guys, they are quite fun.
