I have read that Cardianals are less susceptible to Neon Tetra Disease than Neons are, but I have a Cardinal with classic Neon Tetra Disease - bands of color loss, cysts/bumps appearing etc. I have isolated it to a separate 5 gallon tank and dosed it up with recommended anti-parasitic medication - just hope I caught it in time to prevent spread to my other neons & cardinals. Looking on the black side, if I do lose the whole school, can anyone recommend other schooling fish that can resist this nasty disease? I do already have 6 harlequins that seem very healthy so could increase those I suppose, but if tetra's are out, I would like alternatives too.

Also, I am not sure of the life cycle of the NTD parasite - how long should I wait before considering re-introducing more neons or cardinals?

Thanks!

Any fish in the Tetra family can get the disease, even Angel fish. I wasn't aware there was a med/cure. Only option was to euthanize from what I have read. I have lost a few from it.

Yes - I know that treatment is a long shot but I had an empty tank anyway and thought I had nothing to lose by trying. It is difficult to tell but the affected fish doesn't appear to be suffering too much, but if it looks much worse I may have to put it down. The moral of the story is to use quarantine tanks before introducing anything into an established aquarium - I am not sure where the disease came from but the tetra's were fine for a few months without any symptoms. It must have been traveling on plants bought recently from a LFS - they were mixed in with fish too.

Thanks,
