I am not ready to get a frog yet, but I am looking into my options. I am wanting to find a cage, set it up with live plants and maybe a water fall, and then eventually add 2 frogs.

Cage wise:
I am really wanting to get a 18"x18"x36" zoo med Paludarium, but it is so hard to find them. Petco and Petsmart do not ship or carry them in stores.
This is the 12x12x24 which is easy to find, but I think it would be too small for a pair of WLTF. Would it be okay for 2 WTFs?

I have experience with WTF, but was wanting to maybe try something different. I cannot really find too much information about WLTF as pets, it seems like they are not very popular. Can anybody give me a run down on pros and cons of each type of frog? Maybe someone has WLTF and can share their experience? What should the cage size look like?
