Best Guide to Treat Betta Fish Fin Rot


We will go deeper into the Best Guide to Treat Betta Fish Fin RotThe fins of betta fish are among their most striking characteristics. These graceful creatures’ vibrant and alluring qualities are what give them personality and worth. The fins are frequently the first to hurt for betta, however, because they are also a very sensitive area for them. As a result, betta fish have very visible fin decay.

Owners of betta fish most frequently struggle with fin rot. This has fins that are tattered, torn, or gradually missing. Fin edges are frequently jagged, thinned, and black.

The caudal or caudal fins are where most fin decay occurs. There is a color change to begin. Although the decay frequently appears black, it can occasionally appear white. Actually, the black parts are dead tissue. In extreme situations, the tail may bleed or merely appear to be missing.

Why Does Betta Fish Fin Rot Occur?

Both good and bad bacteria can be found in aquariums. Betta fish typically are not harmed by microbes unless their immune system is weak. When the aquarium is not properly maintained, the microbe population increases dramatically. Betta fish with rotting fins have an excessive number of gram-negative bacteria or pathogenic fungi in their environment.

Ammonia, nitrites, and nitrates are substances that naturally occur in waters, particularly from fish feces and residue. Fish are also in grave danger from it. As a result, regular water changes and aquarium cleaning are crucial.

The same is true of betta fish. Don’t use it; these lovely fish deserve better than to live in a tiny box tank. Furthermore, keeping an aquarium for betta fish shouldn’t be too challenging. Your betta will remain content and healthy with routine tank cleaning and water changes.

Sometimes, cutting back on food is all it takes to reduce the amount of poop. Fish that are overfed have more waste floating around in their environment, contaminating the water. Food must still be distributed sparingly.

Betta fish may already be infected when purchased from fish stores occasionally because they have been kept in the same tank for a long time. In relation to germs, there are various pathogens that cause the disease fin rot.

These include the pathogens Pseudomonas fluorescens and Vibrio parahemolyticus, which can also infect people with weakened immune systems. The latter is even more well-known because it gives humans intestinal flu. However, there are particular pathogens that only affect fish.

Can a betta fish’s fin rot self-heal?

If left untreated, fin rot worsens. Your fish may eventually perish if nothing is done because this illness puts their immune systems in danger.

But don’t worry, antibiotics aren’t always necessary for the treatment of betta fin rot disease. Before you purchase the medication, consider how serious the situation is. Additionally, natural approaches can help betta.

Treatment for fin rot in betta fish


As soon as you are certain that your fish does indeed have fin rot, remove him from the other fish in the tank to avoid contaminating them. To help your infected fish heal, set up an isolation tank where you can add medicine to the water.

then take these actions:

1. Grab a fish salt box

With the right quantity of fish salt in the water, mild betta fin rot can be treated. Compared to table salt found in grocery stores, fish salt or dry sea salt is healthier and more natural. It functions as a natural antibiotic and antifungal.

When treating fin rot in betta fish, use more fish salt than what’s recommended on the box. About 1 tablespoon is used for every 10 liters of water.

Never directly add salt to the aquarium. You don’t want to harm the fish by adding pure salt, which can burn the skin. Therefore, the secret is to first dissolve the appropriate quantity of salt in the water before adding it to the tank.

2. Every day until the fish appear healthy, change the water.

It’s important to keep the environment clean for fish kept in separate aquariums. Every day, keep changing the water, and each time, add the proper quantity of fish salt. The ratios of salt in your solution must be correct since a partial change of about 50% water is sufficient.

Keep in mind that contaminated water will hinder your fish’s ability to heal and might even result in a secondary infection because it still contains microbes that could harm your tiny betta.

3.Add Indian ketapang/almond leaves

Many betta fish owners attest to the antifungal and antibiotic properties of the dried leaves of the native Southeast Asian plant Terminalia catappa. Online retailers offer ketapang leaves for sale.

For a 40-quart tank, one palm-sized leaf is adequate; however, some people use two. The leaves only need to be washed and torn into small pieces. After about a half day, pieces that are submerged in water will sink.

By putting the leaves in boiling water, you can also opt to first darken the water. You can fill the tank with brown water once the temperature is appropriate.

Although the dried almond leaves are natural and safe for your betta fish, some owners discover that they don’t want to completely darken the tank in order to more easily see fin decay.

Ketapang leaves mimic the natural habitat of betta fish, despite the fact that they may not look attractive in your tank. These leaves exude helpful tannins that fish enjoy, and they give your tank a more natural appearance. Even some aquarium owners regularly use tannins to keep their betta fish’s fins from rotting.

4. Hickey Uses a Heater and Enjoys Tropical Temperatures

Betta fish are native to tropical waters. Thus, even the ideal outdoor temperature may cause them stress. A temperature range of 24 to 28 degrees Celsius should be maintained in the isolation tank’s water. The immune system of your fish is weaker if it is lower than that. Fish are stressed by rising temperatures.

5. Pick a water filter type that doesn’t produce current

Avoid water filters with a spout rod or that have a tendency to vibrate and make loud noises because bettas don’t thrive in tanks with the current.

Filters aid in removing nitrates and ammonia from your tank while preserving the proper balance of good bacteria. But don’t go overboard. Smaller than 10-liter betta fish tanks frequently don’t require any sort of filter.

Therefore, within a few days, you will notice changes in your fish’s fins. Your betta’s fin rot may be more serious than you think if it doesn’t heal.

6. Use medication if the issue persists.

You might need to use medications that are sold at your neighborhood ornamental fish store if your betta’s fins are still thinning despite receiving treatment for a week. But here are some options if you prefer to keep it natural.

One such treatment is ParaGuard, which is milder than aggressive antibiotics despite not containing methanol or formaldehyde. The pH of your water is not altered by a daily bottle (or 5 ml) of ParaGuard.

Combining Jungle Fungus Clear (JFC) and Kanaplex is another similar treatment for infection in betta fish fin rot. This medication’s active components are capable of combating both gram-positive and gram-negative bacteria that cause fin rot as well as fungal infections.

For each 40 liters of water, one Jungle Fungus Clear tablet should be used. If you are using a smaller isolation tank, simply cut the tablet off. This dosage lasts for four days. A spoon is used to mix in the kanaplex. For two days and 20 liters of water, one flat spoon is sufficient.

Obviously, you won’t need to perform frequent water changes while the medication is working if you combine JFC and Kanaplex. Allow the tank to rest for a week following the third Kanaplex dose. By this point, the variations in fin decay ought to be fairly clear.

7.Antibiotics for Severe Fin Rot in Betta Fish

Since older or weaker betta fish typically have lowered immune systems, you might be dealing with a more serious infection when fin rot occurs.

There are several brands of antibiotics like maracyn or erythromycin that can treat fin rot in betta fish. Both medications are the same and are primarily used to treat open wounds, fin rot, and fungal infections. A broad-spectrum antibiotic like erythromycin can kill a variety of bacteria.

Since erythromycin is more of a cleansing type of treatment, combining it with an antiseptic like Methylene Blue or Ich-X can be helpful. By doing this, secondary infections may be avoided. It’s crucial to remove your filter before using a treatment for betta fin rot like erythromycin. This includes aquarium-activated carbon, as it will lessen the medication’s effectiveness.

The frequency of water changes containing potent antibiotics should be reduced to once per week. Make sure your tank is properly oxygenated to make the fish more at ease while receiving treatment.

Regularly Test Your Water
Test your water more frequently than once a week when using antibiotics to treat your betta’s fin rot. Test kits are readily available at your neighborhood ornamental fish store and are excellent for determining the pH balance, ammonia, nitrite, and nitrate levels in water.

Be more watchful while receiving treatment
Taking daily photos of your fish is one way to keep track of their progress. The fact that your fish is not moving makes it simple to compare the changes in the picture.

It’s also critical to recognize the symptoms of stress. Lethargy or a lack of enthusiasm for food are indications that your betta fish is being mistreated. Perform a water change after this has occurred and use activated carbon to absorb any residual medication in the water.

You can try again with a different fin rot treatment after letting your tank sit for a few days—it may be less or more aggressive, depending on your judgment.

Can Betta Fish Fins Regrow?

Most people wonder if betta fins will ever grow back once the disease has not advanced and your fish is acting and eating normally once more.

Since betta fish fin rot is quite common, most fish will recover quickly from treatment. The fins will regenerate, revealing white tissue as it does so. These fins will soon resemble the ones they had prior to going bad.

Some owners reserve the use of antiseptic until after antibiotic therapy. The regrowth of your betta’s fins can be accelerated using products like Bettafix, though most people think this is unnecessary.

Preventing Betta Fish Fin Rot in the Future

Do not overstress your fish. Maintain a spotless tank and a strong immune system for your betta. Establishing a schedule for changing the water is a good idea. Create a reminder to change the water. Your betta is depending on you and will be very happy if you do this frequently despite your busy schedule or forgetfulness.

Generally speaking, a pathogen in the water does not cause fin rot in bettas. However, stress or simply not feeling well at all can increase the risk of contracting an infection. Review and steer clear of each of the aforementioned betta fish fin rot causes.

Your betta fish will recover and live happily for four or five years by swimming around in its tank thanks to all the tips and tricks we covered above.
