Fish Health Consulting
Fish disease is generally associated with poor water quality, which makes your fish susceptible to bacteria and parasites that are naturally found in water.
If your koi are abnormally lethargic, sitting on the bottom, gasping at the surface, segregating themselves from the rest of the fish or have their fins clenched to their bodies, these may be signs of illness.
By identifying such signs and acting on them swiftly, you can avoid disasters. When left untreated, it could lead to significant and catastrophic outbreaks of koi parasites, ulcers, fungus or other bacterial infections .
