every few days. Manlongyu needs to change water every two to three days. This kind of fish is not very strict about the water quality and environment. Regular water changes contribute to the healthy growth of Manarowana. The polluted water can't be used to feed them. When the water is polluted, a large number of harmful bacteria will grow in the water, which will infect the fish body, thus increasing their risk of disease. Therefore, for the general family feeding, it is necessary to change water regularly to maintain water quality and ensure the healthy growth of fish.
for Manlongyu Manlongyu needs to change water regularly, but when changing water, we should pay attention not to change too much water each time. Because they can not adapt to the environment of sudden changes in water quality, if too much water is exchanged, it may lead to sudden changes in water quality, which makes them unable to grow healthily. Therefore, in order to provide them with a stable water quality environment, it is enough to change about one third of the water each time.
They are suitable for living in water with PH of 5.8-8.5, hardness of 6-8 and temperature of 22-26 C. The change of water can use the water that has been dried in advance, that is, fresh tap water that has been dried for several days. This can reduce the amount of chlorine in the water, thereby reducing the harm of chlorine to them. When changing the water, you need to use the siphon method to pump water from the bottom of the fish tank and pour the new water slowly into the fish tank along the wall of the fish tank. Don't frighten them by pouring all the water into the jar at once.
