Swordtail Diseases and Treatments
Swordtails are hardy and resilient fish, which are not prone to any particular diseases, although in softer water or bad conditions they can occasionally suffer from white spot or fungus. Either of these is easily treatable with remedies from the aquarium shop, and should serve as a warning sign to increase cleanliness and check water conditions more often. Salt can be used for preventing and curing some diseases, but beware if trying this. Swordtails bred in high salt (sometimes half the salt percentage of the sea) tend to have little resistance to diseases and can die when put into normal fish aquariums.
