Tree frogs vrs. Darts for beginers

[flybyferns]

lol sounds like you have it down to a science. Is there such a thing as a "too big viv," because I found a nice one for a reasonable price and it is huge. Here is a link Terrarium Setup

Is the entire inside lined w/ glass?
If used for tree frogs, all the electrical/heat generating lights etc, would have to be removed from the interior.
How is it ventilated ??
