How to Diagnose

Follow these steps in order. Stop when you identify a likely cause and move to treatment.

  1. Inspect the fish for signs of injury or disease.

    Look for any external wounds or signs of infection.

  2. Check the fish's diet and feeding habits.

    Ensure the fish is not being overfed and that the diet is balanced.

  3. Monitor water quality parameters.

    Test for ammonia, nitrite, nitrate, pH, and temperature levels.

    Recommended: Water test kit
  4. Consider the fish's environment and tank mates.

    Check for aggression or stress from tank mates that could contribute to bloating.

  5. Perform a physical examination if possible.

    If you have experience, gently palpate the abdomen for lumps or swelling.

How to Fix It

  1. Adjust the diet to a high-fiber, low-protein food.

    This can help with digestion and prevent constipation.

  2. Reduce feeding frequency and portion sizes.

    Feed the fish once or twice a day, only as much as it can eat in 2-3 minutes.

  3. Improve water quality by increasing water changes and maintaining appropriate temperature and pH levels.

    This can help prevent further infections and reduce stress.

  4. Consider using a probiotic to support gut health.

    Consult with a vet for appropriate probiotic use.

  5. If there are signs of infection, treat with an appropriate antibiotic under veterinary supervision.

    Do not use antibiotics without a professional's advice to avoid resistance and harm to the fish.

Prevention
