Stress
PossibleSudden changes in environment or aggressive tank mates can stress the fish and cause scale loss.
Genetic Factors
Less CommonSome Neon Tetras may be more prone to scale loss due to their genetic makeup.
How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Observe the fish's behavior and appearance for any other signs of illness or stress.
Look for signs like clamped fins, loss of appetite, or cloudy eyes.
- Check the water parameters using a test kit for ammonia, nitrite, nitrate, pH, and hardness.
Ensure the water quality meets the Neon Tetra's requirements.

Change 25-30% of the water every week.
- Administer a suitable medication for parasitic infections, following the manufacturer's instructions.
Use treatments specifically for ich or other common parasites.
- Adjust the diet to include a vitamin and mineral supplement to support the fish's immune system and scale health.
