? Manlongyu is a freshwater fish, because they are mainly distributed in Thailand, Peninsular Malaysia and the interior of Indonesia, belonging to tropical freshwater fish. Manlongyu is a small ornamental fish, because of its gorgeous body color and mild personality, it is now welcomed by many fish friends. Manarowana has a strong ability to adapt to the environment and can survive at a low temperature of 14 C, but the lethal water temperature is 11-12 C. Moreover, their demand for oxygen is not high, and if the dissolved oxygen in the water is low, they will surface to breathe by themselves.
does Manlongyu like? Manlongyu does not have too high requirements for water quality, as long as the water quality is clean, refreshing and neutral. You can't use the tap water that has just come out, because the tap water contains a lot of chlorine, which will affect the health of the fish, and you need to be exposed to the sun for 2-3 days before you can use it.
If there is a circulating filtration system, the water can be changed once a week. If there is no filtration system, the water needs to be changed twice a week. When the temperature is high, it is better to change three times a week. Manlongyu does not need to change too much water each time, just control it at one third of the total water volume. When changing water, we should also pay attention to the temperature difference. The temperature difference between new water and old water should not exceed 2 degrees Celsius.
