I am raising koi. Tell you a few points of attention, do these points, your fish are absolutely lively:

1, stocking density should be small, that is to say, the tank as little as possible to put fish.

2, fish water, before entering the tank must first sun or trapped water. Exposure to the sun for a day, or drying 3 days, the purpose is to remove chlorine, which is very important.

3, when changing water, pay attention to the difference in water temperature, the difference in water temperature is more than 2 degrees, koi adapted to 5-30 degrees Celsius, but can not adapt to the sudden change in water temperature.

4, the best tank is a bare tank, that is to say, the tank can not put water plants, sand, stones and so on.

5. Koi eat a lot of food and excrete a lot, there must be filtration equipment and oxygenation equipment.

6, depending on the water quality, usually 3 days to change the water, each time to change one-third of the water.

The above is my experience in fish farming, which is definitely worth referring to.
