White Spot
White spot, also known as ‘ich’, is a relatively common condition caused by the protozoan parasite Ichthyophthirius multifiliis in freshwater fish.
Although this is often considered as a minor problem these parasites can cause significant damage to sensitive tissues such as the gills, and can even kill fish if left untreated. Treatments are available from pet and aquatics shops. However the aquarium or pond water will need treatment as well as the fish so again expert advice should be sought.
White spot often occurs in conditions of poor water quality and over crowding, so this should also be checked and remedied if necessary.
