Many of us have kois that intermittently come to the surface to have a gulp of air and these kois otherwise appear well. I wonder if this action is really benign or is it a symptom of some underlying condition (like mild gill disease)? If one observes the action closely it appears like the kois are "flushing" their gills.

Your comments and experiences will be appreciated.

Thanks.
