Arowana is a relatively common ornamental fish. It is an osteoglossidae fish, but also an ancient freshwater fish. It generally lives in the upper waters, and the requirements for water quality and temperature in the living environment are relatively high. It has obvious appearance characteristics, side body, mouth whiskers, like dragons, so it is called "dragon fish". Its distribution range is mainly in tropical and subtropical areas, and it is distributed in many continents, such as South America, Oceania and southeastern Asia, which are widely distributed.
When breeding arowana at ordinary times, you need to pay attention to whether to put salt in the water. Considering that arowana is a freshwater fish, do not like too high salinity, so generally speaking in peacetime farming is not necessary to put salt in the water, you can use normal tap water, but need to be used after the sun. It should be noted that the water temperature and PH value should not change dramatically. However, considering that bacteria can not be eliminated without salt, attention should be paid to ensuring water quality, that is, changing water in time, or using filters after poor water quality.
Although you don't need to add salt at ordinary times, you still need salt when the arowana is sick. After they get sick, the common treatment is to change part of the water, then raise the water temperature appropriately, and then add salt to the water. However, this is only for relatively mild symptoms, if the symptoms are serious, then you have to use special drugs.
