1. Water temperature: Wild carp have low requirements for water temperature, and they can grow in water temperature between 6-30 ℃. However, artificially raised ornamental carp can keep the water temperature between 20-30 ℃, so that they can grow normally. Although they have strong adaptability to the environment, breeders should also pay attention to the temperature difference to avoid more discomfort.

2. Water quality: Carp eat a lot and pollute the water quality seriously. It is best for breeders to prepare a filter for them to slow down the deterioration of water quality. Change the water every 3-5 days to keep the water clean. When changing water, we should pay attention to the fact that the amount of water should not be too large, and it should be controlled at one third of the total amount of water.

3. Feeding: The body color of ornamental carp is bright. Breeders can usually feed them some bumper shrimp, red worms, blood worms, bread worms, etc., so as to keep their body color and make their nutrition more adequate. However, breeders also need to feed some plant feeds regularly, because plant feeds contain more vitamins and trace elements, which can enhance their resistance and immunity.

Ornamental carp can eat, but their biggest function is ornamental, so the meat quality and nutrition are worse than ordinary carp. Moreover, ornamental carp is expensive, and the cost is relatively high if it is only eaten.
