Looks like a great start. I'm curious about the one that's a triangle with the point cut off. Is that listed on your website as to price or just an example of a custom tank you can do?
Just an example of a custom tank. built it out of some scrap glass we had lol
here's a better picture of it
How much would a setup like this run? I'm fascinated by it. 
for the tank, stand, and full hood, you would be looking at around $115.00
