Whitespot in Freshwater Aquariums
Blog post written by Gary | 25 May 2016 | Category: Aquarium maintenance
Whitespot is one of the most common and highly contagious diseases found in freshwater aquariums and without treatment can cause a loss of fish.
Having an outbreak of Whitespot in the aquarium can be caused by a water temperature difference when changing aquarium water, water quality when introducing new fish and possibly introducing too many fish too quickly into an aquarium.
Whitespot disease is easy to identify as the fish will have very small (sugar grain size) whitespots over the body. Other symptoms include fish gasping at the water surface and a change in the fish behaviour. If left untreated the infection will spread to other fish in the aquarium and the fish already infected will be become re-infected leading to more white spots on the fish.
Whitespot disease is caused by a microscopic parasite which will leave an infected fish to multiply and find other fish to infect. To effectively eradicate the disease from the aquarium the parasite has to be killed in its free swimming state.
As soon as Whitespot is detected it is best to treat the aquarium to stop the disease spreading. The best treatment we find is Waterlife Protozin which when used as directed will usually clear a Whitespot problem in one application. As with any treatment in the aquarium, all carbon or chemical removing media will need to be removed from the filter during the treatment.
During the Whitespot infection the fish may be prone to a secondary fungus or bacterial infection which will also need to be treated. Fish that have survived an attack of Whitespot will be less susceptible to another outbreak.
Some fish, particularly clown loach seem to be more susceptible to Whitespot. These fish will normally give you the first indications if there is a problem in the aquarium.
