My fish (koi) are sick and rubbing. What to do?

Your fish (and koi carp) may have parasites. This is a symptom that can actually be encountered. Unfortunately, not possible to be certain of the diagnosis in photos (different types of parasites for different treatments).

I advise you in a specialized store with one of your fish so that we carry out a microscopic examination to detect the cause. If you cannot travel with your koi carp, here are the contact details of a specialized veterinarian who will make the trip: STIJN VERBINNEN - 0476/88.97.03

It is important not to perform blind treatment without being certain of the disease or parasite or parasites present on your koi carp and fish.
