Health & WellbeingWhats a low cost treatment for my infected fish with ich that already have the white spots on them
Gradually increase the water temp to about 80 F. This will speed up the lifecycle of the parasite. Once all the spots have dropped off the fish, you can use a commercial ich treatment. Look for one in the aquarium section of the local Petco. Follow label directions carefully. If you have just a few fish in the tank, you can remove them to a separate tank after the spots have dropped off. Leave the main tank empty for 4 days at 80 F. The ich parasite cannot survive without fish, so they will die. After 4 days, perform a partial water change, vacuum the substrate, wipe down tank furniture and return the water temp to normal. Acclimate the fish to water temp before returning them to the water.
