Instructions
Observe your fish for signs of diseases. Watch for trouble breathing, decreased appetite, mucus covering the body, spots, sluggishness, visible worms, or your fish scratching itself on rocks, plants and gravel.
Use a commercial parasite treatment based on the type of parasite that has infected your tank.
Watch for signs of "ich." Look for white spots on your fish and your fish scratching itself against other objects. Do not quarantine the fish. Use a formalin and malachite green based commercial medication. Follow label instructions for dosing amount. Continue dosing your fish after symptoms have subsided for another four doses. Avoid temperature fluctuations that may cause flare-ups.
Watch for signs of dropsy. Look for red scales and swelling that causes a pinecone effect. Remove the infected fish from the main tank and move it to a separate tank. Add 1/8 teaspoon of Epsom salts per 5 gallons of water. Repeat this treatment daily until symptoms improve.
Watch for visible external parasites, such as anchor worms and leeches. Remove visible parasites from the fish using tweezers. Use a cotton swab soaked in mercurochrome to treat the infected site to prevent infection. Use a commercial copper remedy treatment according to package directions.
Do a 30 percent water change weekly to prevent diseases and parasites. Allow new water to sit overnight so that it will dechlorinate. Ensure that the water temperature is the same as the current water to prevent shock to your fish. Use a vacuum siphon to clean the gravel or sand at the bottom of the tank. Clean any decorative ornaments or plants in the tank.
