Thank you for the kind words.
I too am using the Red Sea Nano filter...16GPH...it's perfect for this little tank.
Tiny thing even has flow control even though mine is set at max, Betta doesn't seem to mind. Anyway my glass cover jutts out more than 1/2 inch because of the heater. My light is a Coralife Mini-Freshwater Aqualight, got it on sale for $25.

Initially I was going to go with the matching Perfecto 12" hood and a screw-in type compact flourescent but when I discovered the Coralife, I figured it was a better value. The Perfecto incandescent hood was $10, add a good quality full spectrum compact flourescent screw-in bulb and you're looking at $18. It's made of plastic with a plastic reflector.
The Coralife on the other hand comes with
two 9W bulbs, built-in ballast, aluminum reflector and chassis, and clear sliding acyrlic bottom cover. The price of the two bulbs alone is already $12 so the fixture itself is only a few dollars more than the Perecto + compact combo. It's small too only 9" wide. On my tank I disabled one of the bulbs because I don't need that much light so when it's time to change the bulb I just need to enable the fresh new bulb.
