FIN ROT 🐠 Fish Disease Prevention and Treatment

About Fin Rot
Fin rot is one of the most common diseases we encounter in the fish keeping hobby, and it is especially common in bettas and goldfish. It is a bacterial infection that starts out attacking the fins of the fish, and it is important to catch this disease in its early stages, as more advanced stages of fin rot, can be difficult for fish to recover from.
Symptoms
The main symptoms of fin rot are the fraying of the edges of the tail or fins, the fin edges may have turned white, or black, inflammation at the base of the fin, and part of the tail or fin may appear to have rotten away. Other symptoms may include a loss of appetite, lethargy, or you fish sitting on the bottom of the tank.
Causes
There are a few different types of bacteria that are responsible for this disease, some gram positive and most gram negative, and it can be spread from infected fish to healthy fish, so when bringing new fish home, it is always recommended to quarantine them before adding them to a community tank.
In our aquariums, poor water quality, overcrowding, fish injuries, and stress can be major causes for infection.
Prevention
The easiest way to prevent fin rot is by maintaining good water quality.
Keeping up with routine water testing and maintenance is a must to make sure that water parameters are where they need to be for the species of fish you are keeping. Always do your research, as species water parameter requirements can vary dramatically.
Making sure your tank is not overcrowded is also very important for prevention, as keeping a tank overstocked can quickly cause your aquarium to have poor water quality, and with too many fish in the aquarium, fish may start to show aggression towards one another, and could become overly stressed. Even in a properly stocked aquarium, if you notice aggression between fish, they may need to be separated, to prevent injuries and stress.
And lastly, take care not to overfeed your fish, as overfeeding can also quickly lead to poor water quality.
Treatment
Treatment for this disease can be a lengthy process, and depending on how far along the disease is, it may require antibiotics. And as a quick disclaimer, some species of fish cannot tolerate certain treatments, this is often especially true for scaleless fish, so always research the species of fish you are keeping, before you begin treatment.
If caught early enough, doing large water changes of 40 to 50% and adding aquarium salt can often be an effective treatment. The typical dosage for aquarium salt is 1 tablespoon per 5 gallons.
In mild cases, some will recommend also using products such as Melafix or Bettafix to help aid in the healing of the fins.
For severe cases, a broad-spectrum antibiotic may be needed. Products like API Fin and Body Cure which contains Doxycycline, and API E.M. Erythromycin, containing Erythromycin, are often easy to find in most pet stores, at least in the U. S. For those outside the U.S. a prescription from a veterinarian may be required.
The most important part in treating fin rot is always maintaining good water quality, so you may need to do more frequent water testing and maintenance, to be sure you are giving your fish the best chance for recovery.

great video, people need to keep there nitrates low, i raise discus in 4 inch sand beds with lots of plants in 90 gallon tanks, only one pair of discus and 4 cory cats per tank. i do not over stock, nitrates stay below 5ppms and the fish thrive. i see to manny tanks on youtube where people way over stock there tanks.joe h navy seabee

Fin rot, oh no... The only issue I ever had was with white spots and treatment cleared it up quickly.

[@BikesGarage]

Good job 👍👍👍

[@keyrivelasquez2086]

Can I use melafix and api general cure together ? I can’t seem to find the answer anywhere and I would like to start treatment for my fish 😭

[@markhunter2244]

Great advice 🤓

[@mlersk8830]

I have a question- sadly my fish died kind of quickly from fin rot I didn’t catch it quickly enough. So now what I’m looking at it actually killing the Bacteria in the tank that caused it- rather than treating sick fish. Will a total water change- and adding aquarium salt kill the bacteria in the tank? Thank you!!

[@ChristianF2424]

Yes water change should do it but no need to do a full water change so like %40-%60 should be good and like one spoon full for every 10 gallons I think

[@sandidsaman7723]

can a mild betta fin rot heal on its own without any medication if i keep the water super clean during treatment?

[@edgardocastanares2366]

Yey!! Thanks for this..

[@ulytano4029]

I have a fish with fin rot its not getting worse but her fins arent growing back

[@Chandra-sv2qe]

Thank you so much! My betta is having fin rot and i think it's all my fault 😟 now I'm doing 30% of water change every 3 days, and add almond leaves.. i need to add aquarium salt today. I really hope he gets better 🙏 ty..

[@things.801]

How many tanks do you have?

[@thenerdyfishgirl]

7 currently up and running, redoing a room right now to add a new fish rack.

[@fernandasanchez665]

I have done everything I possibly could do. But my fish is still sick. Everything looks good on water quality. I just don’t know what to do.

[@honeyangel7]

I have a platinum betta fish and tbh after a week hes suddenly has small grey parts on his fin. My husband has thankfully woke up when he was leaving for work and well, saved his life. We are both unsure what to get to treat his fin rot because of mixed reviews. We tried almond indian leaves but they gave us small ones when we were promised big ones. Im unsure where to buy some that are big. Or what sort of antibiotic to use. If someone can help that would be great.

[@lowkeynonymous570]

Quick question, one of my friends gave me their betta and he cane with his fins kind of clamped and one of his fins have a black strip, which kind of looks like fin rot but I’m not sure he doesn’t have a lost of appetite and is swimming around and eating pretty well

[@elenamirosanu4233]

thanks, you help my fish to not die and help me have the right medinas and it is coming tomorrow😀😁😋😊

[@alejandra.05]

I need help so my goldfish woke up this morning with a red spot in between its eyes what should I do!!!

[@anandbabu7137]
