Panting Fish?

While caring for fish here at ECHO, we always stop to observe and look for issues in an aquarium if we see a fish "gilling hard" or flexing it's mouth with each exaggerated action of the gill flap. This behavior indicates some sort of stressor in the environment. The stressor can be aggression from another fish, it can be a pathogen taking hold of the fish or it can be a water chemistry problem. Now, this change in gilling rates is being used to detect deteriorating water chemistry in water supply systems for people. The new canary in the coal mine.
