Poor Water Quality
Most LikelyHigh ammonia or nitrite levels can overwhelm the fish's gills.
Water Temperature Fluctuations
Most LikelySudden changes in water temperature can cause stress and rapid breathing.
Dietary Issues
PossibleOverfeeding or poor diet can lead to obesity and respiratory problems.
Poor Tank Conditions
PossibleInsufficient space or overcrowding can cause stress and breathing difficulties.
External Parasites
Less CommonInfestations by parasites can impair gill function and lead to rapid breathing.
