Why is my fish isolating itself?

Your Koi could have a parasite or a bacterial infection.  It should be netted and inspected.  If you need a treatment, you can use MinnFinn for parasites or Tricide-Neo for an ulcer. 

Minnesota Koi keepers may contact Dr. Amy Kizer at Lexington Pet Clinic if they have a Koi with a health problem.

If you live elsewhere and require assistance, get in touch with a veterinarian that specializes in Koi health in your area or an AKCA certified Koi Health Advisor.
