Pristella Tetra Bloated or Swollen: Common Causes

Internal Bloating

Most Likely

Overeating, constipation, or an accumulation of gas can cause internal bloating.

Infection

Possible

Bacterial or parasitic infections can lead to inflammation and swelling.

External Trauma

Possible

Physical injury from tank ornaments or aggressive tankmates can cause swelling.

Poor Water Quality

Less Common

Ammonia, nitrite, or nitrate levels that are too high can stress the fish and cause bloating.

Disease

Less Common

Conditions like dropsy or swim bladder disorders can result in bloating and swelling.

How to Diagnose the Cause

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

  1. Inspect the fish for any visible signs of injury or trauma.

    Look for cuts, abrasions, or changes in the fish's coloration.

  2. Check the water parameters for ammonia, nitrite, and nitrate levels.

    Use a test kit to measure these parameters.

    Recommended: Water test kit
  3. Monitor the fish's diet and feeding habits.

    Ensure the fish is not overeating and that the diet is appropriate for its needs.

  4. Observe the fish's behavior and swimming patterns.

    Changes in behavior may indicate pain or discomfort.

  5. Conduct a physical examination of the fish for signs of internal swelling or bloating.

    This may require a veterinary examination.
