Swimming sideways in Bala Sharks can indicate serious health issues, often stemming from internal parasites or poor water quality. It's an urgent condition that requires immediate attention to prevent further complications. As Bala Sharks thrive in large, spacious freshwater tanks, maintaining optimal conditions is crucial to prevent such behaviors.
Common Causes of Swimming Sideways in Bala Shark
Internal Parasites
Most LikelyInternal parasites can cause inflammation and interfere with the fish's swimming ability.
Poor Water Quality

- Perform a full physical examination
Observe the fish for other signs of illness, such as loss of appetite, scales standing out, or clamped fins.
Recommended: stethoscope or null - Check water quality parameters
Test for ammonia, nitrite, and nitrate levels. Also, ensure pH and temperature are within the optimal range for Bala Sharks.
Recommended: pH test kit, nitrate test kit, nitrite test kit, thermometer - Conduct a Fecalysis
An examination of the fish's feces can help identify internal parasites or other issues.
Recommended: microscope or null - Assess tank conditions
Look for signs of aggression, overcrowding, or inappropriate tank decorations that might be causing stress.
- Consult veterinary records
If this is a recurring issue, review previous treatments and observations to guide the current approach.
How to Fix It
- Improve water quality
Increase water changes, add beneficial bacteria, and treat with water conditioners to reduce ammonia, nitrite, and nitrate levels.
- Medicate for internal parasites
Administer a suitable medication, such as fenbendazole, under the guidance of a vet.
- Treat for infections
Use antibiotics or antifungals as prescribed by a vet for bacterial or fungal infections.
- Reduce stress
Ensure the tank has ample space, remove aggressive tankmates, and create a stable environment to reduce stress.
