The trigger for this viral disease is Rhabdovirus carpio (RNA virus). It mainly occurs in spring when the temperatures are between 10 and 20 degrees. This disease is often due to the koi’s unfavourable living conditions. Raising the temperature to above 20 degrees and adding vitamins to the food with JBL Atvitol can help. Adding AccliPond helps to regenerate the destroyed mucous membrane and protects the koi sustainably.
Important information: Once affected, the fish remain carriers of this disease throughout their lives, even without ever exhibiting symptoms themselves. Typical signs include: bloodshot spots (at the edge of the fin), apathetic behaviour and also pop-eyes. Direct treatment with medications is not possible at this stage. The best thing is really to prevent rather than to cure, since the disease is often avoidable when ideal living conditions are present from the start. This applies to both the food and the water values.
