for goldfish to eat bubbles on the surface of the water? It is not normal for goldfish to eat bubbles on the surface of the water. When you see the goldfish floating to the surface of the water to eat bubbles, it means that the water quality in your fish tank has been very poor, the water has been seriously anoxic, which can not meet the normal needs of the goldfish, forcing the goldfish to float to the surface of the water to get as much oxygen as possible from the air by eating bubbles. Generally, this happens mostly because of the following reasons:

one is rainy days, low air pressure, oxygen in the air is difficult to enter the water. The other is because of excessive feeding at ordinary times, resulting in residual bait and goldfish excrement, which seriously pollutes the water quality. In addition, there is no filtration system and no long-term change of water for goldfish, resulting in water quality in the fish tank and unsuitable for the growth of goldfish.

2. how to solve the problem

of goldfish eating water bubbles? Goldfish eat water bubbles mostly because of lack of oxygen in the water, so to solve this situation, it is necessary to input enough oxygen for goldfish in time. This can be done by changing the water to improve the oxygen content in the water. It should be noted that when changing the water, the amount of water should not be too much. One third of the water should be changed at a time. The water temperature of the new water should be close to that of the old water to avoid changing the water temperature to affect the health of the goldfish. The other is to supply oxygen to the fish tank through the oxygen supply system to quickly provide oxygen to the goldfish.
