I recently had a couple neons die from neon tetra disease. i have been lucky enough to see that my 1 lonely little neon has not(tha i have seen) touched the other fish before it died i any way. The only other fish i have in the tank left are my 2 danios(i lovvve them!) and the 1 neon and a snail. I am praying that the danios dont get it. Is it common for them to get it, or is it rare? Thanks i love my fish!
