Fin Rot
Symptoms:
Fish may have deteriorating fins, often with red or white edges. Secondary Fungal infections often occur.
Cause:
Bacterial infection caused by Aeromonas and/or Pseudomonas bacteria often precipitated by poor water quality, low water temperatures, or a combination of both.
Treatment:
You will first want to determine the specific cause of the illness, so check your water’s quality Ammonia, Nitrite, pH, and Nitrate levels as well as the temperature. Be sure to provide optimal water conditions and the correct water temperature for the species of fish you are keeping. Treat with Kanacyn, Tetracycline, Furacyn, Nitrofura-G or Penicillin. Basically, you want an antibiotic specific for Aeromonas and Pseudomonas bacteria. The use of a medicated food is also wise. Treat the fish in isolation (i.e., quarantine tank) if only one fish is sick. If not, the whole tank should be treated. In either case, water conditions must be improved and proper temperature maintained for all fish. Adding salt to the water may be helpful.
The success rate for treating Fin Rot is good providing the illness is caught early and water conditions are kept optimal. Left untreated this infection can be deadly. Early treatment is essential! Once treated, fin tissue lost to this illness will grow back providing the fin rays and/or fin bases have not been damaged.

Fin or Tail Rot (see photos) Fins that are badly torn or frayed for reasons other than fighting will usually indicate fin or tail rot. Fin or tail rot is a bacterial disease that usually attacks weak or minimally damaged fin edges. Once established, the bacterium consumes the fin as it works its way up toward the fish's body. This causes the fins to appear frayed or ragged or in severe cases nearly stubs. Frayed fins can also be a sign of water problems in which case the pH, ammonia, or nitrites are too high. You should check your water conditons before treating. The best prevention is to maintain accurate water conditions. Sometimes the salt level will be too high. This can cause the effects of fin-rot. Symptoms: The fish's tail or fins are ragged, frayed or appear to be shrinking or decaying. Goldfish may have red streaks in their veiltails. Treatment: It is best treated with an antibiotic. There will be one best suitable at your local pet store. Make sure it states that it treats Fin or Tail Rot. In some cases a secondary infection or fungus will appear. If this is the case, treat the fish for the fin rot and then proceed to the fungus problem.(back to top)
