I was meeting with one of my professors in his office and saw a nano tank on his book shelf. I asked him about it and he said it was his officemates. Anyways it looked to be one of those 5 gallon plastic mini-bows with the integrated filters, I didn't see any extras like a skimmer and what not. It was stocked with an anemone and a clown fish. I guess he must have changed out the stock bulb with a compact flourescent and added a small heater somewhere. But my main question is it really possible to setup something like this on the cheap and would it be stable if stocked liked this?
