Here is my current "Best" aquarium, a 37G tall:
This is my Peppered Cory breeder tank, which also houses my Zebra Danios. My favorite feature of this tank is the Finnex Ray2 light. Once I decided to make fish my hobby, we bought the light and our plants have been going nuts. I know that I have little in the way of aquascaping here, but I've only been doing this a few months. This tank started as something to keep my wife company while I work and go to school (long hours). This tank is a Tetra SafeStart success story!
My main hint to other aquarists is a basic one: Do your regular maintenance as you should! My fish are healthy and happy because I do water changes weekly and clean my filter often.
