Hello,
Last week I added a school of 6 cardinal tetras to my tank which were promptly harassed by zebra danios (see my other thread). I found two tetras dead the next morning, and I assumed it was just from the danios nipping at them. However, I've been watching the tank more and the danios seem to have left them alone. Three of the remaining four tetras have died in the last couple days, and the last one doesn't look so hot.
After I started paying more attention, I noticed that all of the cardinals had white spots. My first reaction was immediately ich, but within hours, they started losing their color from the tail fin to about 1/3 of their body. They also had a lot of trouble swimming properly (they would basically be swimming at a downward angle), and most of their fins looked pretty damaged. Once I noticed the color going, the fish would usually die within the day.
This sounds a lot like Neon Tetra Disease, but I was under the impression that cardinal tetras were immune. What else could have caused this? I have danios, gouramis, and cory cats still in the tank, and now I'm really nervous that I'm going to lose the whole thing.
Thanks
