Fin rot's a condition whereby bacteria attack a fish's fin or tail. Fin rot almost always occurs as a secondary infection. This means the bacteria that cause fin rot, which are everywhere, can cause infection only if the fish is already sick or injured. Fin rot eats away at a fish's fins and will often destroy the fin all the way down to the base. Fin rot manifests as a ragged, fuzzy edge to the damage fin.

In most cases, fish will regrow their fins and tails, often looking just as good as the originals in most cases. However, if you let fin rot go on too long -- and it does progress quickly -- more serious infections can set in and kill the fish. Usually if you treat fin rot before it completely eats away at the tail or fin, the fin will grow back normally. Most fish and grow their extremities back quickly and completely if they're in a clean fish tank. The symptoms of bacterial tail and fin rot in goldfish are obvious. The fins are frayed, with red streaks and pink edges.

A fish with fin rot will have ragged, frayed fins. Both the fins and the tail may be affected. The edgesof the fins are often discolored (sometimes lighter, sometimes darker). 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.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.Fin rot is characterized by damage to any of the fins. This may include small holes (pinholes), ragged or frayed edges, transparent or thin sections of fin, fins falling apart in chunks, edges turning white, black or red, slimey looking areas, or inflamation of the fins or fin base. In crowntails, rays may thin or break off. If left untreated, the fins will become shorter and shorter over time, and fin rot may progress into the body. In advanced cases, the fish may have bloody patches.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.As for adding the fish that may have a possibility of having fin and tail rot, I would not recommend it. I would keep it isolated and keep treat it as you are before adding it.
