What Is A Discus Fin Rot Disease?
Discus fin rot disease is a medical condition in which the fins of the discus appear to rot or decompose such that the fin begins to black or brown and sometimes even white. It comes about due to bacterial or fungal infection to the fish.
Fin Rot Symptoms
- The edges of the fin or tail begin to turn either black or brown.
- The base of the fin becomes swollen.
- The fin might become rotten, or huge lumps of it might begin to fall off.
- Fins appear to have white dots on them.
- The edges of the tail or the fins begin to look tattered.
- The fins might have holes through them.
Following these symptoms is a loss of appetite, less action, or movement as discus begins to sit at the bottom of the tank, not making any attempts to swim or do anything.
Discus Fin Rot Disease Details And Causes
The rot of the fin begins at the edge of the fin; it moves up from there, damaging any tissues in the fin in succession until it gets to the base of the fin, which might be deadly and unsalvageable.
Fin rot is a resultant effect of an infection relating to either bacteria or fungus.
- Bacterial Infection: When fin rot is caused by a bacterial infection, the fin of the discus will decompose or get rotten in a way that looks rough and raggedy.
- Fungal Infection: If the cause of fin rot is a fungal infection, the rotting of the fin will look even, and the edges of the fin will look white.
In some cases, fin rot could be as a result of both bacteria and fungi infections, and this could be brought about a number of reasons which include:
List of all possible causes
- Dirty tank.
- The poor condition of the water in the tank.
- Poor diet.
- Contact with already infected fishes.
- Injuries arising from improper handling of the Discus.
- Injuries arising from fights with other fishes in the same tank (nipping among fishes).
- Fin rot can even be a secondary disease brought on by another disease.
How Long Does Fin Rot Take To Heal?
The amount of time it will take for fin rot in the discus to heal is dependent on how severe the fin rot disease is. If the fin rot only affects the edges of the fins or tail, the discus will begin to recover its lost tissue and grow back its fins within a period of 4 to 5 days with appropriate care and treatment, which must begin as quickly as possible. However, if the fin rot disease has not affected most of the fin but has yet to get to the fin base, proper care and treatment should see the discus to good health in a few months.
When the condition worsens, it might be best to give in to euthanasia, so the discus does not have to swim or do anything more stressful.
Discus Fin Rot Treatment Steps

[STEP4] – Test Water Parameters
After cleaning everything, put back everything, fill the tank with water.
Examine the conditions of the water in the tank and test for such things below for both the main aquarium and the hospital one at the beginning:
- The level of pH (~6.5 and Hardness 4.0)
- Water temperature must be between 80º – 86º Fahrenheit (around 29º – 34ºc).
- Use dechlorinated water, because most municipals add chlorine to their water to make it clean.
- Test ammonia using ammonia special test kit.
- There should be zero amounts of nitrites.
- The level of nitrates should be no more than 40ppm.
[STEP5] – Put Back Discus
