As for "land" It depends on what sort of maintenance you feel like doing!

Creating divided areas of the tank to allow for both water and terrestrial substrates is an easy and inexpensive Do It Yourself project. This is almost a necessity if you plan to include live plants on land.

The basics are described here:http://www.frogforum.net/vivarium-te....html#post9063

Another method is the "pile of rocks" which is just as easy. Simply pick out some slate from the local garden store and silicone or Gorilla Glue it in place. Add live moss and you are done!. I cheat a bit here and use PVC pipe sections and straight unions to make stable spacers for hides. If I am really bored at work I occasionally craft acrylic "tables" to support stone too. You can also incorporate cork bark and wood this way!

While this enclosure is obviously not for frogs() this was the technique I used for this tank:

(If you look closely, you can see one of my acrylic tables hiding in there.)
