in the water is the most common reason for goldfish to spit bubbles on the surface of the water, because in the process of raising goldfish, there are many reasons that can cause lack of oxygen in the fish tank, such as food residues polluting the water quality, excessive density of goldfish breeding, low air pressure and insufficient oxygen in the water, which may lead to lack of oxygen in goldfish. At this time, the oxygen on the surface of the water is relatively abundant, and the goldfish will come to the surface to breathe. At this time, the fish tank can be oxygenated by changing the water, or the oxygen pump can be used to oxygenate the water.
, the water quality is bad, the acidity and alkalinity change, the goldfish is possible to spit bubbles to the water surface, at this time can change the water to improve the water quality.
of water temperature When the water temperature changes, goldfish may also spit bubbles on the surface of the water. This requires special attention to keep the water temperature stable when raising goldfish, after all, the stability of the water temperature is very important for the health of goldfish.
, occasionally there will be goldfish because of their own reasons, by spitting bubbles to maintain the balance of water pressure and body pressure, so as not to damage the internal organs. This situation is generally rare.
, goldfish is more sensitive to feed, when it is not palatable, goldfish will spit out, but also spit bubbles, such as feed particles are larger, goldfish can not swallow, it will continue to spit out, and accompanied by spitting bubbles. Therefore, when feeding goldfish, the feed must be carefully chosen, and it is better to choose some high-quality feed with small particles to feed.
