To me...by the time they hit an inch they didn't seem so delicate. Keep her in a small tank (ten gallons is fine). I keep my temp setups really simple. I have a moist paper towel on the floor, a single medium size pothos in a pot and a water bowl that I raised off the ground so the crickets couldn't crawl in. At night I would put in about ten small crickets. I stopped the fruit flies by the time the frogs got that size....although the drosophelia hydei are larger and would probably be a good size. In the morning I would take out the paper towel and count any remaining crickets. The tank was easy to clean, baby frogs can easily find food and you can monitor what they eat.
