Great buy! Looks good in your home already. This is the tank I want for my next display tank.
I'd offer that this footprint is the best choice for a PAR38LED pendant. (see my 40g sig line) If DIY electrical isn't an option, you can use a gooseneck fixture either made for a Tank or a drafting table fixture. I've also see people use the floor lamps design for reading. The nice thing about the PAR38s is the bulb base is standard size.
