One of my rummy nose tetras is showing some discoloration on the back. It
looks like a white patch, with no visible texture to it (eg no bumps or
"cotton" growth). This has appeared overnight, after a large water change
(1/3 of the water). For pictures of the sick fish, go to:
These guys are pretty elusive and hard to photograph. For reference, the
other healthy tetra has a much darker back. Other than the white patch, the
fish is eating and acting normally. What kind of disease could this be?
Should I separate this fish?
The parameters before the water change: pH 7, ammonia 0, nitrite 0, nitrate
40 ppm. The nitrates are fluctuating a lot, I've been trying to keep them
down.
The tank is 20 gallon with live plants, and AquaClear 300 power filter. The
inhabitants are: rummy nose tetras (6), rasboras (6), neons (2), cardinals
(2), male guppies (7), platy (1).
I've never seen anything like this before. Please help.
Thanks.
