Hey Poly, I've had my Tomato frog for a little over 2 weeks now, and I can certainaily vouch for there resiliance. Mines actually gained some size and become fairly bold in a short space of time.
I keep him at 72-73f during the day, and it drops to about 68f at night.And twice daily mistings. Horacio, as he/she is named, has gone from a dull rusty leaf colour to a solid deep orange. And seems so far to have a steady appetite.

Hope that helps you a little
