First, to have a relatively large water body, the width of the fish tank is more important, because the adult of the silver dragon can reach 80cm. It is suggested that the width of fish tank should be at least 55cm, and the narrow space will limit the growth of silver dragon.

Second, fish should be raised with water first, and good water quality can ensure the health of arowana. The filter tank should be covered with filter materials as far as possible, such as ceramic ring, bacteria room, time ball, etc. The only difference is the length of use, and the effect of cultivating bacteria is good. The more filter materials, the more nitrifying bacteria, and the better the effect of decomposing toxins.

Third, diligence is very important. Change the water frequently at ordinary times, and change at least 1/3 of the water every week. Fresh water can promote the growth and metabolism of yinlong. The cotton filter element of physical filtration should be washed at least once every two days, and it must be replaced after a long time, otherwise it will easily breed harmful bacteria.

Fourth, the breeding is diversified. Usually frozen loach, small fish and shrimp are the staple foods, and occasionally insects are fed as snacks. Here, I need to remind you that live food is easy to carry parasites and eggs, and fish will get head holes, internal delivery, external delivery, enteritis and other diseases, which is very troublesome. It can kill parasites after freezing, which is safe and hygienic. Hey, be civilized before you feed.

Do the above, parrot fish and arowana will grow up healthily ~
