My very humble setup and my Whites Tree Frogs...

Very nice.

Those spots are so cute . Mine both have some spotting too. Before you do the false bottom you should look into turning that tank into a vertical tank. I believe there are kits sold to convert? Essentially in the end the tank would look similar to a tall exo-terra. There would be more climbing space and the false bottom wouldn't take up as much vertical space. You would need a temp home for you frogs when doing this though (like a hospital or quarantine tank). Part of the fun of having frogs is being able to craft such awesome enclosures, like Poison's.
