Ready for Red-Eyed?

[Surrealasm]

Doing some research on Red-Eyed tree frogs... I see that on the recommended care sheet provided from this site, the author claims to have successfully housed 2-3 adult red-eyes in a 10 gallon aquarium.

Is this recommended? Or is that overpopulating?
What experience do you guys have with this?

From what I have learned the rule is 10 gallons per frog but more room is always better.

I am sure you can maintain a pair of frogs in a ten gallon tank but what a boring life they must have.

Tree frogs in the wild don't have a short leash and the more you can provide in confinement the more entertainment value you will receive from the frogs in which you keep. Height is going to be of most importance here since their living environment in the wild is stories above the ground floor.
Myself, 20 gallons minimum for two tree frogs with the home being higher than it's width is always the plan.
