As the disease progresses, the fins become increasingly eroded, and the infection may even reach the fish’s body, causing redness and ulcers.

Treating Fin Rot

Improve Water Quality

The first step in treating fin rot is improving your aquarium’s water conditions. You can do this by performing regular water changes, monitoring ammonia and nitrite levels, and ensuring proper filtration.


If the situation isn’t improving or worsens, you may need to opt for medications or antibacterial treatments to combat the infection. You can try products like API General Cure, which are safe for most fish and invertebrates.

Preventing Fin Rot

Proper Tank Maintenance

Regular tank maintenance, such as water changes and cleaning, can prevent the build-up of harmful substances, ultimately preventing fin rot.

Another way to avoid fin rot is to ensure compatibility among tank mates. Aggressive fish or those that nip fins can lead to fin damage and infection.

Now that we’ve covered the basics of fin rot, let’s address some frequently asked questions:
