KOI carp diseases.
If our fish get diseased, it is necessary to ask for help of a veterinarian specialist or the breeder from whom we purchased the fish. Especially in spring, it is necessary to observe the awakening fish carefully and to check their reaction to feeding. If the fish „sits“ near the bottom and has no interest in feeding, there is something wrong. Similarly, a fish should not keep away from the shoal of other fish. Moreover, if the fish has its pectoral fins laid along the body, it may be already late for therapy.
