goldfish keep opening their mouths in the water? Goldfish keep opening their mouths in the water may be due to lack of oxygen. Because the process of obtaining oxygen in goldfish is to open and close the mouth and gills alternately, so that water can enter the mouth continuously, pass through the pharynx, reach the gill cavity, and finally discharge the water to the outside with the gill hole. Usually they will open their mouths, but if they open their mouths frequently, it is mostly because the dissolved oxygen in the water is low, so the process of obtaining oxygen will be accelerated. In addition, they keep opening their mouths, which may be caused by bacterial infections caused by poor water quality. Keepers need to observe whether the mouth and gills of goldfish are bloodshot or ulcerated, if so, it is likely to be caused by this.
that goldfish keep opening their mouths in the water? If it is because of the lack of oxygen, you can try to change a large fish tank to reduce the feeding density, so that goldfish have more space to move. It can also change water in time to increase the dissolved oxygen in water. Oxygen pumps can also be installed, and the power of oxygen pumps can be increased at night to avoid hypoxia caused by low air pressure. If the water quality is not good, you need to change the water immediately. If you find that the mouth or gill of the goldfish is ulcerated, you should isolate and treat it. You can take a medicated bath with yellow powder every day, or you can add salt to the fish tank and raise the water temperature to 28 degrees. Change the water every day, and you can recover in about a week.
