What is fin rot, and how is it caused?
Fin rot is a condition caused by pseudomonas, vibrio, and aeromonas bacteria.
However, the primary reason for fin rot disease is stress and inadequate tank condition.
Fin rot disease is easily preventable but is challenging to cure.
You must know that fin rot disease is contagious if caused by bacterial infection.
If your guppy fish is infected by fin rot, it can be dangerous for the remaining fish in your guppies tank.
What are the symptoms of fin rot disease?
There are two types of symptoms to detect fin rot disease:
- Physical symptoms
- Behavioral symptoms
The edges of the fins get discolored and appear milky at the early stages of fin rot. However, it is not noticeable in the early stages until it starts becoming worn at the fin’s edges.
With time, the infection will spread, and your guppies fin pieces will start to fall, making an uneven tail shape at the edge.
You will notice that the fins of your guppy are getting shorter and shorter over time.
The affected spot of your guppy will become red and swollen.
So these are the symptoms of fin rot disease in guppy fish:
- Milky edge
- Frayed fins
- Swollen Fins
- The whole fin is rotting away.
These are the behavioral changes your guppy fish will show when suffering from fin rot disease:
- Your guppy fish will become lethargic.
- Your guppy fish will stay at the bottom of the tank.
- Your guppy fish will lose its appetite and will avoid eating.
Your guppy fish will become weak and inactive when struggling with fin rot disease.
You will notice your sick guppy avoiding swimming with other fish and resting at the bottom of the tank.
Your guppy will lose its appetite and avoid feeding on food in most cases.
Symptoms of bacterial fin rot and fungal fin rot
Bacterial fin rot
Your sick guppy fins will have ragged rotting fins in case suffering from bacterial fin rot.
Fungal fin rot
If the reason behind fin rot is fungal, you will notice more uneven fins of your sick guppy.
Also, your sick guppy fin will become milky at the edges, showing the symptom of fungal fin rot.
In most cases, both types of infection are seen together.
Symptoms of Mild, Major, and Severe fin rot
|Mild Fin Rot||Major Fin Rot||Severe Fin Rot|
|Guppy fins will get darker in color||Guppy fins will get extremely darker in color and will develop white fuzz on the fin’s edge (If fin rot is due to fungal infection)||This is also known as body fin rot.|
|The tips of the fin will change in color, appearing white, brown, or grey.||You will notice a large amount of your guppy fin has been rotted.||At this stage, the fin of your sick guppy will get entirely eaten up.|

How to treat fin rot disease in guppies?
To treat fin rot disease, we have to know the severity of the disease.
If your guppy fish is suffering from mild fin rot, then you don’t have to isolate the sick guppy, and you can treat your guppy in the main tank.
However, if your guppy is suffering from major or severe fin rot, isolating the sick guppy is essential.
Follow these things to treat your guppy fish in the main tank:
- Clean the tank by siphoning out all the solid debris from the bottom of the tank. Such debris will act as food for the bacteria.
- Perform 35% water change with fresh water.
- Run a check on water parameters to ensure that the chlorine, nitrite, and ammonia remain at 0 ppm and nitrate under 25 ppm.
- Now, you can run the medications by consulting with the veterinarian. Usually, an API stress coat will do the work, but consult your veterinarian first.
- Ensure to remove the carbon from the filter as it will eliminate the medication process.
- Once your guppy fish regain health, add the carbon to the filter.
Fin rot disease can make your guppy fish suffer a life-threatening condition if not treated early.
Also, fin rot disease is contagious, so your other healthy guppies and tankmates will be vulnerable to fin rot disease.
Follow these steps to treat major and severe fin rot in your guppies:
- Isolate your sick guppy fish in a hospital tank.
- Run the antibiotics to treat fin rot.

Isolate sick guppy
Moving your sick guppy to a hospital tank is essential to keep the other healthy fish safe from the infection.
Fin rot diseases are contagious and will spread all over the tank if you don’t move the infected guppy to a separate tank.
Make sure to keep the water parameter of the hospital tank as same as the guppies tank.
Run the antibiotics
Run the medication according to the cause behind the fin rot.
If the cause behind fin rot is a bacterial infection, then run antibiotics like Seachem ParaGuard or Maracyn.
You have to treat your infected guppy with special medication if the fin rot is caused by fungus.
If the reason behind fin rot is ammonia burns, ensure good quality water.
We recommend following the instruction given in the medicine box for knowing the correct dosage and how to apply it. Also, consult your fish veterinarian before running any medication.
Make sure of these things while treating major and severe fin rot in your guppies:
- There should not be any solid debris present in your guppies aquarium as the bacteria use such debris to feed themselves. So siphon the substrate to extract all the solid waste from the tank.
- Keep a regular check on water parameters and ensure that the chlorine, nitrite, and ammonia remain at 0ppm and nitrate under 25ppm.
- If you are using aquarium salt to treat your sick guppy, ensure performing a 100% water change every day and don’t put the aquarium salt twice in the same water.
- Make sure to provide the water temperature between 72-82 °F.
- Perform a 100% water change of your main aquarium and clean it, so other fish will not suffer from fin rot.
