which has the same floor space as the 40 gallon but is about 25" tall. I think the lack of having a visible screen (and reachable, since mine liked to hang from it) that is quite low, makes the dragon feel a little less caged. I also like the taller one because even though my guy doesn't climb any higher than he needs to to bask (which is basically the same height as in the old tank), I am now able to put branches in sort of vertically instead of horizontally. Since the old tank was only 16" tall, I couldn't get any limbs that were thick enough that I didn't have to lay on their sides. This took up a lot of space, and now I just have a piece of grapevine resting sort of vertically (about 50 degrees or so to the floor) that is oriented so the lower part is under the basking spot and the higher part is a little bit out of the way of it, and a piece of cork bark that is rested up against the branch so that it creates a hiding spot and a basking platform. It works out quite nicely and leaves a lot of open floor space for a cage that isn't that big.
The only real downside to getting a taller cage is that they can be harder to heat. Mine is easier though, because it's a lizard lounge which has the vents on the sides and a glass top (with a couple vents on top, and a screen section that the matching UV lamp fits into). The basking light is actually in a fixture that they sell that fits into one of the top vent's holes, keeping the light inside the tank, so the heat is enclosed. Since heat rises...blah blah blah...you get it. With a screen top you will either need a much higher basking spot or a higher wattage bulb. Another problem I see is that with mine the basking spot is fairly low, so when he is basking the UV light is about 16" away. He still benefits from the UV light being there, but not quite as much as if he could get within 6" of it or so. I give him his supplements though.
hope I helped a little
