There are many identified causes of fin rot. Fin rot itself can be a disease or a symptom of a more serious health problem but the root cause of this disease starts from the environment. It could be caused by other fishes in the aquarium. Because fin rot is a disease caused by gram negative bacteria such as Vibrio, Pseudomonas and Aeromonas, it can be transmitted to other fishes through physical contact and infected aquarium water. In other cases, a fish nips the tail and fins of other healthy fishes. This can become infected and result to fin rot.

Fin rot is caused by a bacterial infection (e.g., ). Sometimes fin rotbegins after an injury to the fish's fins or tail. This could be due to fighting with otherfish in the tank and having their fins torn or injured.Tail and fin root is a fish disease caused by bacteria. Normally, this disease will not infect healthy fish living in good conditions, but poor health and poorly kept aquariums are not the only causes of tail and fin root. It can for instance be caused by injuries and other fish nipping the fins or just generally bullying them; all which weakens the fish in a way that allows tail and fin rot to infect them. This means that it isn't very hard to prevent or at least minimize the risk of tail or fin rot in your aquarium. All you have to do is to keep the aquarium clean and well kept; the fish healthy and well fed, and only combine fish that gets along well. Tail and fin rot can also be caused by Tuberculosis which can be harder to prevent. It is important to determine the cause of the disease when treating it and rectify the problem otherwise the disease might return within a few weeks.

The main symptom of fin and tail rot is exactly what the name suggests; that the fins or tail starts to rot and disintegrate. In severe cases there will be nothing more than stumps left of them. The disintegration of the fins often leaves exposed fins rays and the disease can also cause an irritated area around the base of the find and bloody edges on the fins. Tail and fin rot can also generate symptoms on other part of the fish body such as skin ulcers, loss of color and cloudy eyes. The skin ulcers usually have red or gray edges.

External treatment by antibiotics is usually enough to treat this disease but the disease can be internally medicated as well. Which option you choose might depend on the size of your aquarium etc as medicating the water in a large tank can be expensive. If you choose to internally medicate your fish you should mix 1% antibiotics (chloromycetin /chloramphenicol, tetracycline or other similar antibiotics) in the food. Make sure that the fish eat the medicated food. If you decide to medicate the water you should add 20-30 mg per litre water of the same antibiotics I mentioned above for internal treatment.The bacteria that causes fin rot is normally present in the aquarium, but usually doesn't infectthe fish unless they are injured or stressed in some way. Fin rot is an opportunistic infection. Once thefins are torn then a bacterial or even a fungal infection can easily invade the injured tail or fins.There’s nothing more depressing than waiting months or even years for your angel fish to develop those beautiful long flowing fins only to see them slowly flake off and wither into nothingness. The fish swimming through those flakes must feel they’re in a special snow globe o’ hell. Luckily, as long as you are paying close enough attention to your fish, fin rot can be easy to diagnose as well as treat. Otherwise, if you happen to have gotten sucked into a week-long Sponge Bob marathon, fin and tail rot can end your fishy’s little life.
