Discovered one of my bristlenoses is looking quite unhealthy, carrying a fuzzy white shag-pile carpet on its back.
We've just been through a major move and the guys had to spend four days in a 20L bucket with 75% daily WC's.
Filter seems to have come through fine, kept the media wet and mobile throughout transfer. UV filter (new lamp) and Seachem Purigen reactor are both going strong.
Water chemistry seems ok, GH & KH good, almost nil measurable nitrates and nitrites. PH around 6.9 to 7.1. Nobody else in the tank (180L, 5x Goldies, 9x tetras and 5x BNs) is carrying any unusual carpet and all seem quite healthy.
I'm thinking a fight over new territories and move stress has sparked this.

The real question is treatment. She's been isolated into her own tank with plenty of airstone so I'm free to treat as needed.
Salt? Melafix? Temperature? Doug?
