Fish feeding step

1. Environment: 80cm×50cm×45cm aquarium, with a single culture length of 5- 10cm, which can be stocked12-14; If the body length is more than 20cm, 4-6 fish can be kept, and it is not allowed to be mixed with small fish such as traffic lights and lotus lanterns. The principle of collocation is to give priority to fish, and other collocation fish should be male and female or paired. The density depends on the size of fish, and the total number of fish should be controlled at 6- 12.

2. Water quality: If it is a filtration system, change the water every 2-3 days. Suck out feces, residual bait and other dirt at the bottom of the box and the water at the bottom with a straw, and the water exchange rate is 1/3- 1/2. The changed tap water is first treated with dechlorination agent, and a water purification tablet is added every 10kg, ground and melted, and then stirred for half a minute. Fine sand and aquatic plants should not be laid at the bottom of the aquarium, but pebbles can be placed to prevent the water quality from deteriorating due to excessive excrement deposition. The map fish consumes a lot of oxygen, so it needs to be equipped with a submersible pump with three functions: diving, oxygen spraying and pumping, which is turned on 24 hours a day and the water temperature is 22-26 degrees Celsius.

3. Feed: feed cladocera zooplankton, earthworms and artificial compound feed in the juvenile stage, and feed small fish and shrimp, frozen fish and shrimp minced meat and artificial feed in the adult stage. Feed regularly, 2-3 times a day. Artificial feed should be eaten after 10 minutes, and the residual food and feces floating on the water surface should be fished out with net bags to prevent water pollution.

4. Light: 2-3 hours of light every day can make the body color of map fish more gorgeous, and at the same time, it can sterilize and prevent fish diseases and water quality corruption.
