There are many possible causes of fin rot in aquarium fish. The most common cause is an incorrect water chemistry.

Fin rot is also caused by poor water conditioning, poor diet, and stress. Poor water chemistry can be caused by high levels of chlorine, ammonia, or nitrites.

Poor water conditioning can be caused by poor filtration, high levels of dissolved minerals, or inadequate temperature control. Poor diet can be caused by a lack of fresh food, poor quality food, or insufficient vitamin and mineral supplements.

Stress can be caused by overcrowding, poor water quality, or inadequate light.

Fin rot is a common ailment in fish that is caused by a variety of different bacteria. The most common type of bacteria that causes fin rot is Aeromonas hydrophila, which is found in both fresh and salt water.

Fin rot can also be caused by Pseudomonas fluorescens, Vibrio vulnificus, and Edwardsiella tarda. Fin rot is often the result of poor water quality, as the bacteria thrive in dirty and stagnant water.

Fish with fin rot often have frayed or ragged fins, and the tissue may be discolored or have white patches. In severe cases, the fins may disintegrate entirely, and the fish may die.
