I have used acriflavine, but it did not do much. Do you have any recommendations of good anti-fungals? I have never had fungus before (except on eggs) and am a bit nervous about it. I have seen it in fish stores

After two week of that tank being clear (plus the several clear days in quarantine), I thought I was in the clear and introduced some otocinclus. I think maybe one had a little cyst or something. (I trusted the source and did not quarantine. I regret this now!) This second reinfestation may not be the same as the first. This one is acting more like ick. Now that I have had it for several days, I have gotten a chance to look at it. The spots are more hesitant to leave the fish and there are more of them. I don't know. I will continue Formalin treatment and external parasite treatment and salt in quarantine. If it's ick, it will not be here long! =) If it is something else, well, I'll just keep trying...

Thanks!
