A goldfish's abdomen may swell due to several reasons, including overfeeding, constipation, or a bacterial infection known as dropsy, which is characterized by fluid accumulation in the body. Additionally, swim bladder disorders can cause buoyancy issues and abdominal swelling. It's essential to monitor the fish's diet and water quality, as poor conditions can exacerbate these health issues. If swelling persists, consulting an aquatic veterinarian is recommended for proper diagnosis and treatment.
Carbon dioxide causes the abdomen to swell, which lifts the abdominal wall away from the internal organs. That way, the doctor has more room to work.
