Third Place
This is an attractive planted community tank but I don't think it depicts a "natural" or "biotope" type theme. Both the fish and the plants are from different continents though there are no obvious incompatibilities.

I very much like the choice and use of driftwood and the water in this tank is much clearer than that in the other two tanks in this class. The tank would benefit from a little more trimming to allow light to reach better into the tank.

No plant system is discernible no reference to a
natural biotpe. May the plants used give enough
Oxygen for the fishes.

Additional Information Aquarium is set up as a "killi-kommunity". Actual measured water volume is twenty-five U.S. gallons. It is hoped that the killies will spawn enough to maintain the species in the presence of other small fishes. Fine-leaved stem plants and a spawning mop is used for spawning sites. Algae is allowed for the benefit of the Otos, and any infusoria and protozoans that may develope as food for fry and any other grazing critters. The substrate consists of four layers. The bottom-most layer is a mixture of sand, peat, vermiculite, red art clay, and worm castings. The next layer up is a thin layer of fine sand to keep the bottom layer in place. The third layer up consists of unwashed Flourite. And the top layer is a mix of Flourite and Onyx as needed for decorative purposes. The substrate ranges in depth from three inches(left front) to nine inches(right rear). One piece of red slate is used to support and hold the lowest wood layer in position. Fertilization consists in the use of Seachem's Flourish Iron, Water Conditioner and Tabs.
