Argenta, Your tank looks great,
I have a few questions about it if you dont mind,
Is it a solid and steady/strong?
Is the heat tape/pad hidden in a slot? Or just underneath and does it touch the bottem, or is it raised a little like having a edge around it or feet?
does it hold humidity and heat well? like will it escape easy like a tank, or is it pretty easy to keep in?
And lastly do you use heat tape? and does a peice of correct size keep the whole tank warm at the correct gradient once on thermostat?
Anyway, sorry for all the questions.
I was thinking 14" because i always see mine climbing the branch he has, Maybe he thinks hes a GTP.

I figured for 5 bucks 2" would give it a little more, but if its more trouble then worth then i wont.
But it does look great and helps a ton, Thanks.
