I have two grey tree frogs. I have had the first for about 9 months and it hasnt gotten any bigger than it was when I got it. (about 1.25" long) I recently got another one (2.5 months ago) and it was the same size as the other one. However, the new one has grown a lot! (probably 2.25" long now) Is it a female? And if so, could she currenly be pregnant? (pics below) She is constantly looking like she is inflated. But when she sits on the glass parallel to the ground her whole stomach droops to the lower side, leading me to believe she is carrying eggs?...

If she is pregnant, what would be the perfect set-up for her own tank so that she will lay the eggs and everything will be ok?

Any help is greatly appreciated!!
