Additional Information North European ponds in the summertime are teeming with life. This rich fauna and flora inspired me to reproduce a shallow stagnant aquatic habitat in the aquarium. All animals, plants, and decorations, including Elodea canadensis and Ceratophyllum demersum, have been collected from the Beberlini sand-pit in Latvia (coordinates: 56° 33' 52" N 21° 1' 10" E). Canadian Waterweed and Hornwort are invasive species in Latvia, but at present they are common in ponds, ditches, and lakes. I have, therefore, decided to use them in my tank.
The coldwater aquarium must keep the water temperature below 20 °C. This was done by installing additional cooling fans in the tank lid.
