How To : Cure Bacterial Infection

  1. Identify the symptoms: The first step in treating fin rot is to make sure your fish have it. Symptoms include frayed or disintegrating fins, whitish or grayish patches on the fins, and possible reddening or inflammation around the fins.

  2. Test water parameters: Check the water parameters of the tank, including pH, ammonia, nitrite, and nitrate levels, as poor water quality can contribute to the development of fin rot. Make sure the water is within the acceptable range for your fish species and perform a partial water change if necessary.

  3. Isolate affected fish: If you have multiple fish in your tank, it's important to isolate any fish showing signs of fin rot in a separate tank to prevent the spread of the infection. Make sure the tank has a filter, heater, and enough space for the fish to swim comfortably. Heat the tank to a temperature comfortable for the species of fish you are treating.

  4. Purchase Maracyn 2: Maracyn 2 is an antibiotic medication that can be effective in treating fin rot in freshwater fish. You can purchase it online here, or in store at MastahBetta Fish Shop.

  5. Follow the instructions: Follow the instructions on the Maracyn 2 packaging carefully, as the dosage may vary depending on the size of your tank and the severity of the fin rot. Generally, the medication is added to the aquarium water at a rate of 1 packet per 10 gallons of water. Each packet treats 10 gallons of water.

  6. Turn off carbon filters: If you are using a carbon filter, turn it off before adding the medication to the tank, as it can remove the medication from the water.

  7. Treat the tank: Add the appropriate number of Maracyn 2 packets to the aquarium, making sure to distribute them evenly throughout the tank. Keep the tank lights off during treatment.

  8. Monitor the fish: Check on the affected fish regularly to see if the fin rot has improved. It may take up to two weeks for the fins to heal, but the fish should start to show improvement after a few days.

  9. Do a partial water change: After treatment, do a partial water change of 25-50% to remove any excess medication from the tank. Make sure to treat the new water with a water conditioner before adding it to the tank.

  10. Resume normal tank maintenance: After the water change, resume normal tank maintenance, including regular water changes, filter maintenance, and monitoring water parameters.

That's it! By following these steps, you can cure fin rot in freshwater fish using Maracyn 2 and restore your fish to good health. Remember to always read the instructions on the medication carefully!
