I'm impressed - the power of a water change . Did you think it was fungal or bacterial out of interest if you had to pick?
I know its amazing what a W/C can do...I honestly think it was fungus because it seemed like the more stuff I removed plants, decor, infected fish, filters etc...the better or weaker it seemed to get? If it was bacterial I feel like with out def. Meds it would still be infecting the rest of the fish even if there was nothing left in the tank gravel decor what ever....fungus I feel like you can FLUSH out!!!! Bacteria needs to be treated... IMO anyways...I guess I was lucky it was a Fungus?
