Alright, about a week ago I noticed that one of the barbs (of nine) seemed to have ich - it had the white spots that slowly grew over time and would disappear. Since it was the first disease of the tank, I let it go for about a week or two until I noticed another barb get the same spots. By this time, the tiger barbs were not very active at all (totally uncharacteristic) and were just hanging out without swimming, barely even schooling. Also, when they don't swim, they sit their with faces pointed down, like when they're sleeping - but they're definetly awake.
I've been testing the water, which is fine - ammonia and nitrite are 0. I got ich-x about a week ago and have been using it along with 30% daily water changes. Four barbs died in the last two days, yet for a week none of them have been showing any of the white spots (the last went away about a week ago). My cories are unaffected. This is all in a 29 gallon planted tank, pH around 8.0 (tap water), and temperature around 80 (summer in LA).
If anyone can identify the ailment, how to treat it, how it got in my tank (I haven't added any new fish in a couple of months), etc, that would be fantastic.
