I bought 7 neon tetras yesterday and then noticed that one of them had white spots all over the body so i began treating the whole tank for ick. Today i noticed that one neon died and I can't find another one, probably died too. But the other fish all look sick. The have white spots and the tail seems to be rotting. So now I don't know what to do. Can they have ick and fin rot at the same time? Should i take them out of the tank? I have a molly and a swordtail there as well in a 10 gal tank.It doesn't look good but I want to try to save the neons. Anyone know what I can do? Oh, and the last time I checked the water, it was perfectly fine, the ammonia, nitrite.etc.
