Bloated or swollen Panda Loaches are a serious issue indicating possible internal bloating, constipation, or more severe conditions like dropsy. This problem can be life-threatening and requires immediate attention. Owners must consider water quality, diet, and behavior changes as potential causes.
Common Causes of Bloated or Swollen in Panda Loach
Internal Bloating

How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the fish for external signs of injury or parasites.
Look for cuts, abrasions, or parasites like ich or flukes.
- Evaluate the fish's diet and water quality.
Ensure a balanced diet and proper water parameters (pH, temperature, ammonia, nitrite, nitrate).
- Check for signs of constipation or bloating by gently pressing on the abdomen.
Be cautious to avoid causing injury.
- Monitor the fish's behavior and activity levels.
Changes in behavior can indicate discomfort or illness.
- Conduct a water quality test to check for ammonia, nitrite, and nitrate levels.
High levels can contribute to bloating and internal health issues.

How to Fix It
- Improve water quality by performing regular water changes and maintaining optimal temperature and pH levels for Panda Loaches (20.0–26.0°C, 6.5–7.5 pH).
- Feed a high-fiber diet and consider fasting the fish for 24 hours to allow the gut to clear out any obstructions.
- Administer an antibiotic like erythromycin or metronidazole if dropsy or bacterial infection is suspected, following dosage instructions provided by a veterinarian.
- If constipation is the issue, introduce more fiber into the diet or consider using a laxative medication as directed by a vet.
- Ensure the fish is in a stress-free environment with no aggression from tankmates and provide hiding spots if necessary.
