1. Hypoxia in water: Parrots need sufficient oxygen in the process of feeding, their lips can't be closed, they only have half gills, and their control over water flow is not good, so their demand for oxygen is very high. When the oxygen in the water is insufficient, they will float on the water to breathe.
2. Amchlorine poisoning: When changing water, if tap water that has not been dried is used as new water, it is easy to poison it. Because tap water contains a large amount of ammonia, chlorine and other toxic substances, it is easy to cause poisoning in such an environment for a long time, which also easily leads to them always floating on the water.
3. Infection with parasites: If the water is not changed for a long time, it will easily lead to a large number of parasites in the water, and parrot fish is likely to be infected, thus causing it to always float on the water surface.
2. What should parrot fish do when it is always on the water1. Supplementing oxygen: If the parrot fish always floats on the water due to insufficient oxygen, it needs to be replaced with new water, and a small water pump can also be used to increase the oxygen in the water.
2. Chlorine removal: If it floats on the water surface due to amchlorine poisoning, it is necessary to change the water again. If tap water is used as new water, besides installing filters in the tank, tap water should be dried for 3-4 days to remove chlorine before use.
3. Change water: If it floats on the water caused by parasitic infection, it is necessary to change the water again, and put special drugs in the water to help it remove insects.
