Common Causes of Bloated or Swollen in Adolfo's Cory

Improper Diet

Most Likely

Overfeeding or a lack of dietary variety can lead to bloating in Adolfo's Cory.

Internal Parasites

Possible

Parasites such as flukes or nematodes can cause bloating as they feed on the fish's internal tissues.

Gastrointestinal Blockage

Most Likely

Ingestion of non-food items or indigestible material can lead to a blockage, causing bloating.

Poor Water Quality

Possible

Unstable water parameters, such as high ammonia or nitrite levels, can stress the fish and lead to bloating.

Infections or Bacterial Diseases

Less Common

Infections, such as dropsy or swim bladder disease, can cause bloating as a secondary symptom.

How to Diagnose

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

  1. Inspect the fish's scales for a 'pinecone' effect.

    This indicates a more severe bloating and could be due to dropsy.

  2. Check the fish's swimming pattern and appetite.

    A lack of appetite and swimming at the water's surface are signs of discomfort or illness.

  3. Examine the fish for any signs of injury or infection.

    Injury or infection can contribute to bloating as the body's immune response increases fluid retention.

  4. Perform a water test to check ammonia, nitrite, and nitrate levels.

    Poor water quality can stress the fish and exacerbate bloating.

    Recommended: Water test kit
  5. Consider the fish's diet and recent changes in feeding habits.

    Dietary issues are a common cause of bloating and can be easily addressed.

How to Fix It

  1. Improve water quality by reducing ammonia, nitrite, and nitrate levels.

  2. Adjust the diet to include more fibrous foods or consult with a vet about a possible dietary change.

  3. If parasites are suspected, use an appropriate medication recommended by a vet for Corydoras species.

  4. For infections, treat the fish with antibiotics or antifungal medications as prescribed by a vet.

  5. If a blockage is suspected, consult a vet for medical intervention to remove the obstruction.

Prevention

Maintain stable water parameters, feed a balanced diet, and monitor for any changes in behavior or appearance.

When to Seek Expert Help

See a vet if: If bloating persists despite efforts to improve conditions or if the fish shows signs of severe distress.
