Thank you! I will probably stick to 3 or 4 American Green Tree Frogs. I want a big tank because I am planning to have a beautiful backdrop, a waterfall, and a custom fogger. Plus lots of terrestrial and aquatic plants. I am getting a TetraFauna Viquarium kit for it, so I needed it to be tall enough for Tree Frogs, but also long enough for the waterfall and water area. Also, will they be able to swim well in it?
