Is there any way to sex your tree frog? When we had just one we were told if he called at night (he very much does!) then it was male. But we got another and we bought it without knowing it's sex. I don't care what it is either way, but for naming purposes I'd like to know lol. I read somewhere you can tell by it's feet....but I have a photo of it's feet and I'm still lost. And then I was told by size, but the breeder we bought it from took it in as an adoption so he has no actual idea how old it is either, just that it was healthy as he had it quarantined and tested. So I don't know if it's full grown or not, I just know it's the same size as Gru, except when they are both sleeping the new one is longer and skinnier and Gru is shorter and wider. Is there any fairly certain way to tell?
