How do you stop Betta fin rot?

If the case is fin rot you do not need to worry because you can stop it. We will present a list of things you can do.

  • Clean your tank regularly. Depending on the size of a tank with smaller ones do it every 3 to 5 days. If you have a bigger tank then you should clean it once a week. The bigger the tank is the less probable that the water conditions change dramatically. 
  • If your tank is bigger than 5 gallons practice the water changes at least 25 percent of it every week. 
  • In rare cases, the cause can be an overcrowded tank with fish. That is rare because Bettas are usually alone or with certain kinds. But it is not bad to know that this can also be the cause. What is the case with being overcrowded? Each fish produces bio-load, an organic matter so if the tank is overcrowded the bio-load increases and raises the risk of bad bacteria growing. keep this in mind too. 
  • Food that is not of high quality can compromise the immune system and that can reflect in many problems among which is the fin rot. 
  • Always have a filter to cycle water but be careful because if it is too strong it can cause stress to your Betta. 
  • Once in a while when performing cleaning pay attention to the bottom. Use a vacuum to clean gravel from old food, debris and feces.
  • If you see that the cause is other fish that are fin nipping your Betta, separate them immediately or use a tank divider. Damaged fins can lead to fin rot. 

What is the best treatment for fin rot?

If your Betta is fortunate enough that you notice fin rot at an early stage it is going to be easier treating it.  As soon as you notice it move your Betta to a quarantine tank.  Set up a quarantine tank not bigger than 2 gallons. Providing heated and filtered water in it is essential for your fish recovery. 

Fill the tank with conditioned water to the top. Put a heater, filter and medicine in it. When the water temperature reaches the level needed it is time to move your fish to a quarantine tank. Put the fish in the bag and let it stay for a while in the quarantine tank until it acclimatizes. Then let it out of the bag into the tank. Provide some temporary decorations too. Every two day do a partial water change up to 25 per cent. If you have a filter then you should do a complete water change. When doing a complete water change place, the fish in the bag again, change the water, pour conditioned water, let the fish acclimatize again and let her out of the bag into the quarantine tank. 

The treatment will depend on the stage of fin rot, the condition of the tank and if you housed betta with other fish. The first and the best thing for fin rot is aquarium salt. It works great but like many other medications it should be used precisely when needed. Remember that you shouldn’t use aquarium salt longer than 10 days because it can hurt your fish and cause kidney and liver problems. Use the correct amount which can be read on the product.  This salt will significantly help but not in the severe cases of fin rot. 

The other thing you could do with a severe fin rot is medicine API Pimafix which is anti-fungal or API Furan 2 which is anti-bacterial.  Follow the instructions and use the right dosage of medication in a quarantine tank that is fully prepared in advance. Do not stop using the medication if you see signs of recovery. Do not forget to do water changes as mentioned earlier and do not move your Betta to her home tank before it completely recovers.
