Stress

Possible

Stress from tankmates, overcrowding, or sudden changes in the environment can cause rapid breathing in Corydoras habrosus.

Disease

Less Common

Check the tank water parameters for ammonia, nitrite, and nitrate using a test kit.
Ensure the levels are within the optimal range for Corydoras habrosus.
Recommended: Water test kit
Measure the water temperature and pH level with a reliable thermometer and pH test strip.
These should be within the species' preferred range of 22.0–26.0°C and 6.0–7.0 pH respectively.
Recommended: Thermometer, pH test strip
Observe the fish's behavior and appearance for other signs of illness such as clamped fins or loss of appetite.
