Siamese Fighting Fish Fin Rot
Fin Rot is one of the most common, yet most preventable aquarium fish diseases. It often occurs at the same time
as other diseases and is brought about by a bacterial infection.
Symptoms of Siamese Fighting Fish Fin Rot
One of the earliest symptoms of Fin Rot is that the fins start appearing ragged. As the disease progresses, the
fins become increasingly shorter. Whiteness can be observed at the edges. Cotton Wool, which is a secondary disease
may start developing and will manifest as a fuzzy growth on the fins. If untreated, the base of the fins will start
becoming red and inflamed, with bloody patches resulting.
Causes of Siamese Fighting Fish Fin Rot
Fin Rot is most often caused when the Siamese fish are distressed due to poor water quality, overfeeding,
expired food, overcrowding and rough handling. If the water is not changed regularly, the leftover food particles
and feces will decompose and contaminate the water. If there are too many female Siamese fish in the tank or if too
much food is placed in the tank, even regular water changes may not prevent the disease. The resultant stress on
the Siamese fish, lowers their immunity thus making them very susceptible to attack from the bacteria present in
their water. Only in very rare instances will Siamese fighting fish develop Fin Rot in spite of an impeccably
Treatment of Siamese Fighting Fish Fin Rot
Once Fin Rot sets in, a complete change of water and a careful examination of the conditions within the aquarium
will be required. Take everything out of the aquarium and wash all the decorations and pebbles with hot water. Do
not use soap. Follow instructions for changing the water in the aquarium.
Fin Rot is a bacterial infection and medication is available to cure it. Some medications that have been
successfully used to cure fin rot include Jungle Fungus Eliminator and Tetracycline.
Fin Rot is contagious. Fish that appear uncontaminated should be separated from the fish that appear
contaminated. It is advisable to place the apparently uncontaminated Siamese fish in a separate quarantine tank
until you are very sure that they are healthy. To prevent the disease from being transferred to your other healthy
Siamese fighting fish, do not share nets between the tanks. Also ensure that everything used in handling either the
sick or the quarantined Siamese fish are washed properly in hot water before being used for any other fish.
Prevention of Siamese Fighting Fish Fin Rot
Water & Habitat: The water in the tank should be changed every one to two weeks with all decorations,
pebbles etc. thoroughly cleaned. It is also important to check the ph and the temperature of the water on a regular
basis. All fish, particularly those with long flowing fins such as the Siamese fighting fish, have a tendency to
contract Fin Rot when the temperature of the water is either too low or too warm for sustained periods of time.
Food: Check that the food you are feeding your siamese fish is fresh and do not overfeed. It is far better to
give your fish smaller quantities of high quality fresh food. Feeding your siamese fighting fish too much food at
one time means there will be excess left over food in the water, which in turn will increase the concentration of
bacteria in the water.
Handling: Be gentle and cautious when handling Siamese fish. They are easily
stressed if they are carelessly handled.
Keeping the habitat controlled, clean and stress free is the best way to ensure Siamese's continued health and
the Siamese fighting fish owner's continued enjoyment of this beautiful, showy fish.
