When your fish is afflicted with a fungus, the rotting will emerge more evenly on the fins. Your betta might also have a white edge. Some people may mistake it for white spots or ich (another disease). Fungal infections can only infect your fish if its immune system is compromised.

2. Bacterial Fin Rot

Bacteria are already present in your aquarium. As a result, as a fish’s immune system weakens, bacteria, take a chance and attack your betta. Unlike fungal fin rot, bacterial fin rot hits bettas in a more uneven manner, which can make the decaying appear more ragged.

What Causes Fin Rot?

Poor water conditions are the most prevalent and leading cause of fin rot, as well as practically every other ailment that your betta is susceptible to. Bacteria, parasites, and fungal illnesses thrive under poor water and tank conditions.

Furthermore, stress causes your fish’s immune system to weaken, making them more susceptible to sickness.

Poor water conditions include not only unclean or foggy water or tank, but also the temperature of the tank, as well as any uneaten food or feces in the tank. if the ammonia, nitrite, and nitrate levels are too high it can affect the water conditions making it hard to maintain a nice immune system for the betta.

What are the Symptoms of Fin Rot?

Before you begin treatment, you must be certain of the disease. What if it is something else? You’re probably already aware of the most typical symptom of this condition, which is rotting fins.

Before we go into all of the symptoms, there is one thing we want to make sure you understand. That is, fin rot can progress through several stages, which are outlined below:

Symptoms of Mild Fin Rot in Betta

  • The tips may turn brown, grey, or white.
  • The fins are a shade darker than the rest of the body.
  • The tips could also appear inflamed, painful, or red.
  • Also, the edges may have just started to show signs of wear.
  • Most importantly, the rot will not appear on your betta’s body.

Symptoms of major Fin Rot in Betta

How to Treat Fin Rot in Your Betta?

Depending on when fin rot was discovered, treatment will be simple. If it’s discovered sooner rather than later, however, if it’s discovered later, it may be more difficult to cure. So, after the disease has been identified, the first and most vital task is to determine whether to split the fish into quarantine tanks or keep them in the same tank. If your betta is currently living in a tank larger than 2 gallons, or if it is sharing space with anything else like plants, it is best to relocate it as soon as possible to prevent the disease from spreading.

By transferring the fish to a quarantine tank, you will not only prevent the disease from spreading to other fish and even plants, but you will also be able to examine the diseased fish separately, and other fish in the main tank will not be subjected to frequent water changes. Also, whatever medicine you use to treat your betta will not affect the other fish in the tank.

Setting up a Quarantine Tank

If you already have everything planned out, that’s wonderful, but if you don’t, then follow the steps below to make the necessary arrangements:

It is necessary to guarantee that the quarantine tank is not excessively large; two gallons is the ideal size. This is because a smaller tank is easier to maintain, such as changing its water regularly, and administering medicine is also simple in a tiny tank. Plus, if you can add a heater to keep the tank at the appropriate temperature and a filter to keep the tank clean, that would be ideal.

The first step in setting up a quarantine tank is to add water and fill it to the top with conditioned water. After that, install a heater and a filter within the tank, followed by the treatment medicine (it will be listed below)

After you’ve made these arrangements, double-check that the temperature is set to your betta’s liking, then gently transfer your betta from the main tank to the hospital tank.

Make sure your quarantine tank includes areas for your betta to hide during stressful times. Soft decorations and silk plants can be used.

Before transferring your betta to the hospital tank, be cautious to acclimate it. You can accomplish this by putting a bag full of main tank water in the quarantine tank and letting it sit for about 15 minutes for your betta to acclimate before releasing it.

If your tank has a filter, you won’t need to replace the water every day because you can merely do a partial water change every 72 hours with 25% of the water.

If you don’t have a filter, you’ll have to clean the tank every day by draining all of the water. You’ll perform the same thing by putting the fish in a separate bag, filling the tank, maintaining the temperature, and filling it with conditioned water before re-acclimating your fish.

Which medicine is best for Betta Fin Rot?

Fin rot treatment is determined by the severity of the problem. Also, whether you’ve kept your fish apart from the rest of the community or if it’s in the same tank as others, will affect the outcome.

You can use the following to treat betta fin rot:

1. Aquarium Salt

You may be familiar with aquarium salt. This is one of the most popular remedies among betta owners because it may cure any condition and is especially effective for bettas. The addition of aquarium salt may cause your betta to get stressed, but when used correctly, it poses no threat to the fish.

It should be used only when necessary, just like any other medication. There are a few minor details to bear in mind. Do not use aquarium salt for more than 10 days, as it can harm the fish’s kidneys and liver.

Second, you must always use the correct dosage as indicated in the instructions. Also, keep in mind that aquarium salt will not work in dirty water and will not be as effective in severe cases as it would be in typical ones.

2. Use Betta Fix and Melafix

Medications are another often advised therapeutic option. Melafix and betta fix are frequently mentioned as the best treatments for fin rot. Both of these treatments contain identical chemicals, with the exception that betta fix is a less concentrated form.

Betta fix and Melafix should never be used on betta fish because they harm the labyrinth organ of the fish. As a result, if your fish has fin rot, you should apply aquarium salt. If your fish does not have a labyrinth organ, however, you can take both of the medicines listed above.

  • If you have a filter in your tank, clean the tank to assist keep the good bacteria in and the ammonia levels down.
  • If your tank is congested and you believe it is becoming dirty as a result, move some of the animals to another tank.

  • If your fish’s condition doesn’t seem to be improving after you’ve treated it in this manner, you might want to try a different treatment approach.

4. Treating Major Betta Fin Rot

If your betta has severe fin rot, keeping the water clean won’t help; instead, you’ll need to attempt a stronger treatment to help your fish. If you haven’t already done so, isolate your fish in a different tank.

  • Move your betta to the hospital tank as soon as possible.
  • Keep your tank’s filter clean to keep good microorganisms alive.
  • Once you’ve completed all of this, drain the tank completely and clean everything with warm water.
  • Once you’ve completed all of this, return everything to where it was before you started filling the tank with conditioned water.
  • Separately mix aquarium salt and completely dissolve it in water before adding it to the tank.
  • Perform a 100 percent water change daily and make sure you don’t add aquarium salt to the same water twice.
  • Repeat this process every day for a week, and if your betta improves, the treatment was successful.

If your fish has body rot, aquarium salt won’t help; instead, you’ll need harsher treatment to get rid of the condition. API Pima fixes (anti-fungal) and API furan 2 are two options (anti-bacterial).

  • Move your betta to a quarantine tank once more for this treatment, but this time make sure it is oxygenated. Add a bubbler or an airstone to the tank to help with this.
  • Clean everything as previously, add conditioned water and check for normal water parameters.
  • Give your betta the doses, making sure the treatment is appropriate for its nature, such as bacterial or fungal.
