Probably a little large for my pond, especially since I'm in the middle of town. It looks like they generally get up to about 3.5 inches?
I've been looking at Western chorus frogs, which are tiny at only 1.5 inches. They appear to be more nocturnal, but come out in the evenings to sing, which I would really love. It looks like they are even native in my area, yet I've never seen them, and again I have run into the problem of not being able to find a decent source for tadpoles. Ah well...
