I agree with the above posts completely. When you get a chance check out the gray tree frog care sheet very helpful.

Also when I was wondering on size and space a few people told me here to use these 2 rules... one never mix species
.............two one frog per 10 gallons.

I feed my full grown grey male 3 crickets every other night. and once in a while he gets any house flies I might catch lol.

Oh and make sure the crickets are no wider than the frogs head... better to go a lil smaller than chance any problems.
