A 10 gallon FLAT aquarium?

I've seen these used for baby snakes and scorpions/tarantulas in the past, as well as in petstore racksystems for mice and reptiles(no saying there appropriate for that use), i have one similar to this that i used when i bulk ordered crickets, worked great.
 
I also think it would be a great tank for a Pacman frog.
 
Pacman frogs are cool. They dont seem to do a whole lot. I had a science teacher that had one and he would feed it during my period and put a document camera over the tank so everyone could see it on the projector.

I think that tank would be cool for fiddler crabs or something like that.
It could be a frag tank.
How much was the person asking?
