Disease w/pic

Does anyone know what this is?

It's a young C. paleatus albino in my stocktank. Don't mind the albino, but will it infect my other inhabitants ;)

Diseases is really where i know nothing. I cannot provide any nutrient salt details on the water, as I have no kit at hand. But an 86 L tank with Eheim 2326 cannister 950 L/h, weekly waterchange 40%, pH around 7, dH 10-14. Other inhabitants 14 cories on 3 species.

Seems like the slime is threading, and detritus from the bottom sticking to it. It doesn't do much swimming. No other fish seem affected.

Thanks

I would do a 50% water change and add the recommended dose of Melafix and add an air stone set fairly strong.

Any idea on what it is?
A bacterial infection? - Some kind of inflamation?

[Coryman]

We don't really know what causes the red blotches, other than it occurs as a result of stress whether it be from catching, bullying by other fish or if the water conditions suddenly change, like a nitrate surge or in some cases a pH crash, which can trigger some species to breed and cause stress in others. Also when many Corys are stressed it appears they release toxins (possibly through the skin), which can cause irritation and poisoning.

I don't know of any research being done on this problem at the moment, but it is something that definitely needs working on.

Is this red pest? About two months ago I acquired Qty 6 Corydoras Sterbai, rather large, 2 inches long, and they were wild caught. Five of them died from this disease, looks identical to the above photograph, except on their sides under the scales. A definite bacterial infection that ended with their demise.
The last Sterbai was slightly infected, I did notice the redness but I increased the temperature to the tank to 85 degrees F, performed large daily water changes of 25 to 35%, and kept the fish quiet in subdued lighting with vigorous aeration of the aquarium.
Today that lone survivor is very active, getting rather plump, and schooling with a few more smaller Sterbai.
I found very little information on the web about this disease, other than when you see it it is too late.

Is there nothing we can do?

Thanks
