The size of the fish tank determines how many map fish can be kept. The oxygen consumption of this kind of fish is relatively large, so it can not be raised too much. With 120 * 50 * 50 fish tank, you can raise 40 small fish with a body length of 6 centimeters, when it grows to 10 centimeters, you can only raise 20, when it grows to 18 centimeters, you can keep 4-6, more than 25 centimeters, as long as you raise two.
In order to ensure the healthy growth of map fish, we must pay attention to water quality and temperature. The water quality should be kept fresh, and the amount of water changed in the early stage should be about half or three quarters, so as to promote its growth. Then change it once a week and soak it in baking soda solution for 10 minutes. The water temperature should be maintained between 22-28 degrees Celsius, not lower than 18 degrees Celsius, nor higher than 30 degrees Celsius.
The map fish should be fed regularly, usually 2-3 times a day, and the amount of feeding each time should be eaten in half an hour, so as to ensure that it is full and not too full. There are many choices of bait, young fish feed more water fleas or earthworms, when they grow up, they can feed small fish and shrimps, they can also feed loach, but they must be cut off, otherwise they will drill through the intestinal tract.
Every day, the map fish should be exposed to the sun, usually for two hours, which can make its color more gorgeous, and also prevent the water from decaying. Regular inspection of the fish to see if there are signs of disease, if the performance is abnormal, need to heat up for water and salt, some of the more difficult to cure diseases also need to be isolated, and medicinal bath.
