1. Oxygen deficiency 1. Reason: When the dissolved oxygen content in water is insufficient, goldfish will float to the water surface to breathe oxygen. At this time, they can be observed spitting bubbles on the water surface continuously.
2. Treatment: Put an oxygen pump at the top of the fish tank. If it is rainy, put oxygen into the fish tank for 4-5 hours. If the weather is normal, keep pumping oxygen into the fish tanks until they recover.
2. Water quality deteriorates1. Reason: If goldfish are not changed for a long time or fed too much, the water quality will be bad. At this time, goldfish will feel uncomfortable, and they will float to the water surface and spit bubbles continuously.
2. Treatment method: First, fish out the goldfish and pour out the water. Then soak the fish tank with crude salt solution for half an hour to sterilize the fish tank. Then pour the water in the fish tank and replace a quarter of the water.
3. Disease1. Reason: When goldfish gills are sick, their breathing will be affected and their breathing will not be smooth. At this time, the gills can't effectively absorb the oxygen in the water, which leads to the situation of spitting bubbles all the time.
2. Treatment method: Fish out goldfish and put them in a fish tank for isolation to avoid the spread of germs on them. Prepare low concentration potassium permanganate solution and soak sick fish for 20-30 minutes every day.
