Water Temperature Fluctuations
Most LikelySudden changes in water temperature can lead to stress and labored breathing.
Insufficient Oxygen
Most LikelyLow dissolved oxygen levels in the water can cause the fish to breathe faster.
Internal Parasites
PossibleInfections from parasites like Monogenea can lead to respiratory issues.
Bacterial Infections
