koi to buy depends on the size of the fish tank at home and the size of the koi. If the fish tank is larger, you can buy more. If the fish tank is smaller, buy fewer. Because the growth rate of Koi is faster, and the adult size is larger, if the feeding density is higher, there will be hypoxia.
Normally, an 80 cm long fish tank can raise 3-5 15-20 cm koi, 6-10 10 cm koi, or 20 5 cm koi. If it is raised in an outdoor fish pond, one square meter can raise about 3-5 40 centimeters.
the koi just bought home? The koi just bought home must first pass through the water. You can put the bag and the koi in the fish tank to be raised and wait for 40-60 minutes. In the meantime, if the koi live in a bag that lacks oxygen, oxygen can be reintroduced.
The koi basically adapt to the water temperature in the fish tank after passing through the water. At this time, it is necessary to disinfect the koi. They can be soaked in 20 ppm potassium permanganate solution for 2-5 minutes. After
soaking and disinfection, the koi can be put into the fish tank, but after putting into the fish tank, it is better to observe them for another half hour to confirm that they are not frightened or uncomfortable, and that they can swim smoothly in the water.
