While rapid breathing can be caused by the exertion from fighting, when the fighting is not happening, the respiration rate would return to normal within a short time. If it doesn’t that then points to some systemic issue. For example - I’ll be out of breath from running on a treadmill. If I’m still out of breath an hour after stopping, I have some serious issues.Could the cause of rapid breathing be from the fight?
Do fish need more oxygen like us when they are stressed from exercise?
what about the cloudy eye? Fighting cause this?
