Increase dissolved oxygen in water  Maintaining sufficient dissolved oxygen in water is the key to raising ornamental fish. The first is to change the water once a day (the water is polluted at the end, and the tap water will be turbulent first); the second is to use an oxygen booster pump, which is turned on for more than 1 hour in the early morning, noon and midnight every day and night; the third is to reduce the stocking density.

Maintaining a high level of transparent waste  is beneficial to the feeding and growth of ornamental fish, while meeting the summer demand for ornamental. In addition to changing the water in a timely manner, the residues in the aquarium should be picked up in time and the excrement such as feces at the bottom of the tank should be sucked off. Water temperature regulation  The suitable water temperature for most ornamental fish is 18-30℃. The main method of water temperature control is physical cooling, which can be injected into the well water in an appropriate amount (previously stormed), or add a small amount of ice and build a shade shed (outdoor pond culture).

Reasonable baiting  In the midsummer season, the appetite of the fish is weakened, and the number of baiting should be reduced to keep the fish 7-8 percent full (finished in five minutes). Feeding time Tropical fish compound feed at 9-10 am, 4-5 pm, live bait such as feeding fish and insects in the morning; goldfish can be fed once at 7-8 am
