CATDOLL : CATDOLL: How to tell if parrot fish is lacking oxygen in the fish tank?

If the fish floats to the surface, it means they are lacking oxygen. You should also pay attention to the fact that tadpoles will release toxins.

This is lack of oxygen, and things like this, you have to buy a big fish tank if you want to keep your mouth above water.

If the fish are floating, it means that the fish tank is lacking oxygen and is having difficulty breathing.

As for the fish tank, the mouth of the tank should be as wide as possible. The fish tank should be related to the number of goldfish you raise, not too many. Generally, a fish tank as big as a plate can be used to raise 4-5 goldfish of 5-6 cm. Then the water source selected cannot be tap water (even if it is tap water, it should be settled for two or three days or exposed to the sun for at least 2 days). You can use well water directly to raise goldfish, or use tap water that has been exposed to the sun to raise goldfish, or it is better to use tap water that has been exposed to the sun and add a medicine called "Lingjun powder" to ensure that goldfish can prevent some diseases. When changing water, the temperature difference of the water should not be too large, which will cause adverse reactions in goldfish. Generally, some dirty water at the bottom is extracted every 4 days or so, and replaced with an equal amount of clean water. Especially in the summer rainy season, the air pressure is low, and the oxygen pump cannot be turned off! Pay attention to the adverse reactions of the fish in time and make preparations early.

This kind of fish is very susceptible to lack of oxygen. Lack of oxygen can easily lead to death. If you see the fish coming to the surface to breathe, it means it is lacking oxygen. The fish body turns white and is no longer red. These are all signs of lack of oxygen. When there is enough oxygen, the color returns to normal.

All parrot fish swim in the upper layer of the fish tank and breathe rapidly, which is a sign of hypoxia.

Look at the color of the fish. One time I forgot to turn on the oxygen pump and the parrot became a white parrot due to lack of oxygen.
