It has obvious appearance characteristics. It has a beard on its side and mouth. It looks like a dragon, so it is called "dragon fish".

When culturing arowana at ordinary times, you need to pay attention to whether salt is put in the water. Considering that arowana is a kind of freshwater fish and doesn't like high salinity, generally speaking, it doesn't need to put salt in the water for breeding at ordinary times. You can use normal tap water, but it needs to be dried before reuse. It should be noted that the water temperature and pH value should not change dramatically. However, considering that bacteria cannot be eliminated without adding salt, attention should be paid to ensuring the water quality, that is, changing the water in time or using the filter after the water quality is poor.
Although there is no need to add salt at ordinary times, salt is still needed when 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 mild diseases. If the symptoms are serious, special drugs must be used. （LongYuShiHaiShuiYuHaiShiDanShuiYu，YangShiShiXuYaoFangYanMa）
