Small Arboreal Snakes

While working at the pet store, I have accumulated a decent amount of used tanks. I have two smaller end tanks that would be PERFECT for a 2-3 foot Arboreal snake.

I plan on getting a Rough Green Snake but are there any other smaller size Arboreal's I could get?:confusd:

ATB!

Maybe... I know that alot of ppl keep adults in a 2'x2'x2' cube. Im not sure what the exact dimensions of your tanks are though.

RGS are awesome!
