Hi Charlotte,
I have been trying to obtain some gray tree frogs for awhile - either species. Once they've metamophosed I'd be interested in buying at least a half dozen. I'm curious about where you collected them and if you've raised tads before. Have you had normal rains? I'm in Dallas currently, and used to be able to collect them in Austin, but the ponds are not usually holding water long enough for grays to breed. Strecker's Chorus Frogs breed successfully there each year, but they breed much earlier, before summer conditions kick in. Any way, I look forward to hearing from you. Thanks!
