The reasons why fish stand upside down:
1. When the fish is exposed to the sun for a long time, the fish tail may be injured and it will not be able to maintain balance. The fish should usually be placed in a cool place Raised everywhere.
2. If the water temperature fluctuates too much and the fish cannot adapt, it will also appear upside down. The water temperature needs to be kept constant.
3. When a fish becomes sick, its appetite decreases, its movements slow down, and it may also appear upside down. Timely treatment is required to avoid fish death.
4. Fish groups fight, or jump or hit the tank, causing damage to the fish and causing them to stand upside down. Fish groups should be kept separately to avoid fighting.
5. If the water level is too shallow, it will also cause the fish to stand upside down. The water level should be raised by 30 cm to recover.
6. If you feed too much, food will accumulate in the intestines and stomach, resulting in flatulence and inversion. If this happens, you should stop feeding immediately and then increase the water temperature, which can speed up the fish's metabolism and effectively alleviate this situation.
