Ok, so I really need some input here. I have 7 rasboras in quarantine after seeing possible fungus on 2-3 of their mouths. I treated with Jungle Fungus Guard (columnaris), which did nothing. I then treated with API Fungus Cure. The API Fungus Cure treatment is supposed to be done today. But the affected harlequins still have a white ball on the their lower lip. However, it doesn't seem to be spreading to the healthy ones and all 7 are active and otherwise normal. No sunken bellies either, so I guess they are eating. Can I put them in the main tank? Do I treat again? Maybe with something different?
