I have an irridescent shark who is suffering form fairly severe fin rot that I can't seem to cure.
(FYI - he's the only fish in the 30H tank; He had a buddy but his buddy passed away over the Winter. He's about 5 years old).
He's had fin rot before, but I think that was a result of bad water conditions (my fault not keeping up with water changes). I managed to cure it by getting the water back in shape and treating with "Fungas Clear" which contains nitrofurazone, furazolidone, and potassium dichromate. I've tried two rounds of the Fungas Clear this time with no significant improvement.
Over the last six months I've been doing very well with the water, but he's developed a fairly severe case over the last three months. I've got the PH at roughly neutral, perhaps 6.9 to 7.1. The nitrates are very low at perhaps 5-10 and nitrites are very low at maybe .25 at most. (The nitrates and nitrites were roughly twice that but bi-weekly 25% changes brought them down over the last couple months).
He has the little "trailers" of his fins trying to regrow, but they don't seem to get anywhere are roughly half gone (tail and dorsal fins). He seems to be active and healthy... these fish get lethargic when they are sick but he is active and eating regularly.
Any thoughts on what to try? Is there another antibiotic type treatment that would help?

But if the tank has been setup for 5 years, you could have what is call Old Tank Syndrome.
