Hi,

Has anybody seen a disease that affects only bristlenoses and/or bristlenoses & cories? In the space of 3 days I have lost 7 bristlenoses and 4 cories in one of my tanks, yet the bristlenoses, cories and whiptails in my other tank are fine. The first symptom was that my large bristlenose had beige coloured spots on it that looked like grains of sand, they were still eating fine. The bristlenoses were acting normally although I noticed that my baby peppermints were sitting in the corners of the tank, one of which had it's nose out of the water. I checked the water quality and ammonia, nitrite and pH were all fine. I treated them with a half dose of protozin and a small amount of aquarium salt (<5g/L). The next day I checked the phosphates at the suggestion of a fish shop and found that they were high. Before that days dose of protozin I did a water change with low phosphate water. The next day I added a phosphate absorbing media to my filter to reduce the phosphates and I noticed that the fins of my catfish were ragged. I searched the net, but nothing looked like the spots on my fish and none of the symptoms seemed to match those of my fish. In the next two days there was no improvement and over that time all my bristlenoses, peppermints & cories died, but the white cloud mountain minnows in that tank are showing no signs of any disease whatsoever. The bristlenoses that were removed from this tank 2 weeks before this problem occurred and the whiptails and cories in the other tank are looking to be in excellent health. The are acting normally, feeding well and have no spots. Anyone have any ideas?

So is it white spot????
The problem seems to be contained in that tank only and the white clouds could be ok because they tolerate a low water temperature anyhow.
That's my guess from very little to go on and this is the time of year for white spot to show it's ugly head.

Did the medication you added affect the catfish perhaps? I can't remember if Protozin is "catfish friendly".

I was thinking that as well, but I think you added only half dose for 2 days?

Any idea what is in Protozin, I can't seem to find it mentioned anywhere?

The catfish died because they are closest the ground

The mountain white clouds are more of a cold waterfish

Hi All,
The exact same thing has happened to me, the same white spots came on my biggest male, then came on the babies, I had run out of "MELAFIX" so I had to wait till the next day to get some more. When I came to treat, all 25 babies had died from the infection which I have on good authority was a (fungal infection) not "WHITESPOT". So if this information helps great, all fish were treated with "PIMAFIX" at recommended rate, all fish recovered once treated.
