Reasons for abdominal swelling in betta fish mainly include the following:
Unclean food: If the fed food is not clean, the fish is prone to ascites, resulting in a swollen belly. To avoid this situation, it is recommended to disinfect or freeze live baits.
Deteriorated water quality: Poor water quality can also cause the betta fish's belly to swell. To keep the water clean, it is recommended to change the water regularly, usually once a week. If the water quality deteriorates rapidly, the water change cycle needs to be shortened.
Overfeeding: Excessive feeding can lead to indigestion and then cause abdominal bulge. Appropriately reducing the feeding amount can effectively alleviate this problem.
Variety characteristics: Some betta fish varieties naturally have larger bellies, which is a normal physiological characteristic.
Breeding period: During the breeding period, the abdomen of female fish will expand, which is a normal physiological phenomenon.
Diseases: Betta fish may suffer from diseases such as enteritis and ascites, resulting in abdominal swelling. These diseases are usually difficult to treat, especially in the advanced stage.
Prevention and treatment methods:
Keep the water clean: Change the water regularly to ensure good water quality.
Reasonable feeding: Avoid overfeeding and pay attention to nutritional balance.
Disinfect food: Disinfect or freeze live baits.
Use drugs: For swelling caused by diseases, strong bactericidal drugs such as yellow powder, oxytetracycline or special sterilization can be used for treatment.
Through the above measures, the problem of abdominal swelling in betta fish can be effectively prevented and alleviated.
