Most LikelyHigh ammonia or nitrite levels can overwhelm the gills, causing rapid breathing.
Temperature Stress
PossibleExtreme temperature fluctuations can stress the fish, leading to increased respiration.
Poor Diet
PossibleLack of proper nutrition can weaken the immune system, making the fish more susceptible to infections.
