goldfish can be raised at a water depth of 10 cm. There are many varieties of goldfish, such as butterfly tail goldfish. It is very suitable to cultivate goldfish at a water level of about 10 cm. Although goldfish can be cultured in a water depth of 10 cm, the number of goldfish can not be too large, otherwise there may be lack of oxygen and deterioration of water quality.
2. What should we pay attention to when raising goldfish1. Environmental stability: Goldfish have low requirements for the environment. As long as the breeder keeps their water temperature and water quality stable, goldfish will not suffer from discomfort. If conditions permit, a heating rod can be installed to keep the water temperature in a stable range. A circulating filtration system will also be installed, which can slow down the deterioration of water quality and reduce the frequency of water change.
2, plenty of space: goldfish belong to medium-sized fish, and their body length is about 30 cm in adulthood. Breeders need to prepare a larger fish tank for them, so as to ensure that they have enough living space.
3. Change water: Goldfish are sensitive to the fluctuation of water quality, so breeders should pay attention to the amount of water and new water when changing water for them. If you use tap water, you need to take it out first and expose it to the sun for 1-2 days. Before changing water, it is necessary to adjust the temperature difference and PH value between new water and old water to the acceptable range of goldfish.
4. Illumination: Goldfish like sunshine, but breeders should pay attention not to take too long when basking in the sun, otherwise they may burn their tails. Also pay attention to the intensity of sunlight. Too much light may make them uncomfortable.
