Re: Ich gone; now fungus?

FishNoob wrote:
It seems (in my admittedly limited experience) that every time we treat ich in the aquarium, we then get fungal infections. There are no signs of ich now (treated with King British - seemed to work faster than Protozin) but a couple of the fish now have white patches, including what looks like a ring of white fungus around one or both eyes.

I'm treating with Melafix, which dealt with this last time - but is it common to find that after treating ich, other diseases occur?

(This is the first time we've used King British - before we used Protozin, which should have taken care of the fungus too, shouldn't it? - it didn't though.)

Secondary infections can happen after ich. Ich parasites damage skin and the medicine (often a necessary evil) stresses the fish even more so you get other problems like fungus, finrot, or Flavobacterium. The other thing that happens is that whatever stressed the fish to make them vulnerable to ich makes them vulnerable to other diseases as well.

When you say "every time we treat ich" it sounds as if you're seeing repeated outbreaks. You really shouldn't be seeing repeated outbreaks of ich. If you get ich in your tanks every time you add fish, you need to find a different fish store and/or use better quarantine procedures. If it's not related to new fish, there's something stressing your fish that you need find and fix.

As for the Protozin, it might take care of real fungus but it won't help much with Flavobacterium. It's sometimes hard to tell the two apart without a microscope.
