What would you do with this?

My vipers are climbers, I have a pretty large area (36x28x22) for the 3 of them and they use every square inch of it. I had them in my 12X12 for a short time while I was remodeling cages, and with a 40w red heat spot, I maintained a pretty good temp differential. It was 6-8 degrees difference from front to back.
 
I have 5 and I have had them for a 1 1/2 and they rarely climb even on their hides. I have then as I said in a half 10 gallon. Mine move all over the place but none of them aren't into climbing. It's cool that your does.

I have a Exo Terra that is the 12"x12"x18" that one of these days I'll set up with something. We picked it up cheap and figure that one of tarantulas would use it but I'm not sure. I almost picked up a red crested gecko but some beat me to it.
 
those vipers look cool, but just to mix things up, have you considered mudskippers?

I have on several occasions, but this footprint is totally wrong and inadequate. I may try to convince someone that we should do skippers in the 20 long though. ;)
 
^ I think HN said he didn't want any more spiders. ;)

I agree as cool as mudskppers are that tank would be way too small for them.
