Why do goldfish always float on the surface of the water and how to deal with it?

The goldfish always floats on the surface of the water, probably because of the lack of oxygen in the water, which makes it difficult for the goldfish to breathe, so it comes out of the water to breathe. At this time, an oxygen generator can be added to the tank to increase the oxygen content in the water. It may also be because the water quality is not fresh enough and there is too much dirt. At this time, the water should be changed to avoid the death of goldfish. It may also be because goldfish eat too much food, indigestion, fish floating on the surface of the water breathing, digestion. At this time, we should stop eating and increase the water flow appropriately to promote their movement and digestion.

1. Lack of oxygen

1. Reason: Once a goldfish lacks oxygen in the water, it will float to the surface and try to absorb oxygen from the air. There are many reasons for the lack of oxygen in water. Small tanks, less water, more fish, not timely change of water, hot weather and other reasons will cause goldfish hypoxia.

2. Treatment method: Put an oxygen generator in the fish tank to keep the fish tank continuously supplied with oxygen to alleviate and prevent the lack of oxygen in the goldfish. If there are more fish, you can fish out a few and put them in other fish tanks separately, which can also improve the lack of oxygen.

2. The water quality is too poor

. 1. The reason is that the water quality is too poor. The water contains too much residue and dirt, which leads to the odor and odor of the water, affecting the growth environment of goldfish.

2. Treatment method: Check whether the water in the fish tank is turbid and has a bad smell. Clean up the garbage, food and bait in the fish tank in time. Then change the water in the fish tank as soon as possible, but remember not to put tap water directly, but to expose it to the sun for a day or two, and then change it after increasing the oxygen content.

Reason: The owner does not pay attention to the amount of food when feeding the fish. The goldfish eats too much feed and has poor digestion, so it will swim to the surface of the water and digest with the help of air.
2. Handling method: If this phenomenon occurs, the feeding needs to be suspended first. A wave-making pump can then be placed in the tank to create a small flow of water to encourage them to move and digest food.
