It is amazing how much you can stock in an a massively filtered heavily overplanted tank! This was taken when the tank was 4 months old - by the time I sold it a year later I was removing a bucket of plant trimmings a week. Only time I was able to maintain more than one male betta in a tank! It had a bright light section and a low light section, and over 30 species of freshwater tropical fish. CO2 injection, added nutrients, 4 watts per gallon in the high light section, 2 fluval 405 cannisters, and flourite substrate.
