In addition, there is another rule, do not choose newly arrived fish, because the newly arrived fish after a long period of transportation, just arrived in a new environment, in a period of recovery and adaptation, at this time the fish is more fragile, changing the environment again is easy to cause fish death.

II. Water quality

As the saying goes, "fish culture should first raise water". If you want to raise fish well, you must have a certain understanding of water quality and water temperature. Swallow fish like soft water quality, the pH is controlled between 6.5 and 6.8, the range difference should not be too large, otherwise it is easy to lead to fish discomfort.

When it comes to changing water, swallow fish are more delicate, and it is not too much to change water once a day. 1/4 to 1/5 water can be changed each time, so it is necessary to change water frequently. At the same time, swallow fish prefer old water. There is no conflict between the two. To keep the water updated, tap water can only be put into the fish tank after being exposed to the sun. In addition, swallow fish are tropical fish, and the water temperature should be kept at 28 °.

III. Quantity

The number of swallow fish culture mainly depends on the size of the fish tank and the size of the fish itself, you can refer to the following data: an one-meter fish tank can raise 10 swallow fish with a length of 10-15 centimeters, which affects the appearance and is not conducive to swallow swimming. Be careful when mixed with other fish, do not choose too lively fish, easy to hit the fin of swallow fish, affect the appearance.

Fourth, feeding

The feeding of swallow fish should pay attention to "eat less and eat more". If small fish are fed three times a day, the amount of feeding should be controlled within 3 to 5 minutes, so as not to finish it, so as not to affect the water quality, once in the morning, once in the evening. As for the food can be freely chosen, small fish can choose to feed red worms, harvest shrimp, red worms, etc., you can also feed some bait as an aid. After the adult fish can be fed beef heart hamburger, which is very favorite of fairy fish, frozen water earthworms and bait, pay attention to balanced nutrition.
