This is my largest tank. About 12 years ago, while I was still living with my parents, I convinced my dad to let me build a saltwater tank into one of the living room walls (click on More above to see). After I left for college this tank became rather abandoned, and in the past few years it had been turned into a freshwater tank, with hardly any aquascaping and hosting only half a dozen messy japanese carps.

In December '97 I decided to start an experiment of setting up an almost self-running tank, that could be maintained by me in the one or two times a month I visit my parents. The tank has strong lighting and sand gravel to stimulate plant growth, and a not too dense population of mostly hardy fish. Because my parent's house is in a cold mountain region, this tank is the only one I have that requires a heater to keep it above 24^oC in the winter.
