Pay attention to the regularity of feeding time, just don't feed at will, and be careful not to feed at night, otherwise it will easily cause indigestion. If you forget to feed the fish for something, feed it normally at the next meal.
Keep the water color when breeding, and the weather is sunny in summer. Change the water after four o'clock every afternoon, and each change is about one-third of the total water. Increase oxygen by air pump or water spray at night. If there is a serious floating head phenomenon, hydrogen peroxide can be added to the pool for rescue.

Water source selection and hydroponics
The water source for garden cultivation must be sufficient, the water quality must be good, and it is non-toxic and free of impurities. Rural courtyard with tap water has the best tap water, which is convenient to take water and contains less bacteria, and is most suitable for breeding.
When building aquaculture ponds, it is necessary to install filtration and circulation system devices to promote ecological balance by releasing active bacteria, filtering solid substances floating in water and disinfecting lamps.
Before releasing fish, the pond must be cleaned with quicklime or bleaching powder to kill pests in the pond. Disinfect for about a week, and inject tap water or groundwater after contact.
