Tu Dong Pond is a water body I have dedicated my enry. I have explored different places like rivers, lakes, streams, small creeks but tose were complicated for me to do, so for the competition I surveyed a shallow area of a stagnant pond, I planned and set up an aquarium. For decoration I use the material found in the biotope including background, rocks, sand, plants, animals and water. Currently my tank is also completed in terms of water quality – the temperature and pH are close to natural.

As soon as this biotope has been completed and I decided to use it to communicate with people and to learn more from other people’s experiences. I sincerely thank you all.

Aquarium information

Aquarium description

Set-up date
February 20st, 2022
Aquarium decoration

As background I used the rocks found in the biotope area, I planted aquatic vegetation on both sides to make the tank look more realistic. As aquatic plants was taken Cyperus polystachyos, which is a plant that can live in a flooded environment. And it contributes to the shelter for the fish at the bottom of the tank.

Aquarium equipment

I only use 2 LED Kaiser lights.
Power 5w, light 6500k.

Fish care

I usually feed 2 to 3 times a day and monitor their behavior, because the number is limited, the monitoring is easy and convenient. The fish seem very comfortable and they feel like they are out in the wild.

Fishes:

  • Trichopsis vittata (Osphronemidae) – 10
Plant care

For the Cyperus I use the soil at the biotope site and use sunlight to photosynthesize and grow as best as possible. And the tree has also grown better than I expected – the plant flowers and produces seeds once every 20 to 30 days.

Aquatic vegetation:

  • Cyperus polystachyos (Cyperaceae) – 2
Water care

Since the natural environment I recreated was a puddle of stagnant water so taking care of the water was also very easy. I did almost nothing with the water in the tank because everything was as it was in the wild.
