Questions About Enclosure Height

[Pyxis]

So my baby beardie, Caramel, has finally outgrown her 20 long, and it's time for a new tank. I found an awesome one that swings open in the front so a) I won't have to fight with trying to go in through the top all the time and b) cleaning will be waaayyyy easier. There are two I'm looking at. One is 36 by 18 by 12. The other is the same but 18 inches tall instead of 12. This one literally costs a hundred dollars more for the extra height, which Caramel would probably never use. My question is, is there any reason I wouldn't want to go with the 12 inch one? I know the 18 inch one is recommended, but why?

Are you talking about the exo terra one?

If so...the price difference isn't worth it, build your own or look for a sale

Yeah, that's the one. The only reason I don't build my own is because if I did, I would want to go big, and I don't have the room for that now. Pretty much this tank will be an in between until I get my new place and have room to build a big enclosure. She's just too big for a 20 long now so I need something in the meantime.
