i recently bought a 16g bowfront, and for $150 it came with the stand and hood and lights. they sell them at petco, and you may be able to purchase the hood seperately, just a thought. not sure on the dimentions, sorry ill have to check on that and get back to you. it makes a nice set up for a specimin tank. I put a couple of small seahorses in it! they look awesome!
good luck,
Mermaid
