New frogs. What to get for a beginner/intermediate?

Thanks for the help. I'll try to find a list of plants that I can use and are good for a red eye tree frog.

For an 18 in. cube, would recommend one of the smaller tree frogs or a ground dwelling Dart/Mantella type frog. If you think about it; once you add substrate deep enough for plants and drainage layer, can end up losing around 4 in. of height, even more if false bottom is involved .
