I've been treating Ich in my 20 high(thanks to new fishies) for over a week now. I noticed two fish that had 3-4 white spots and got quick cure(melachite green and formalin) later that day and gave them the first dose. I've been doing a 25% water change with vacuuming before giving them a 3/4 dose every day. Since then the spots disappeared from the first two sick fish, appeared on 1 of my tetras, reappeared on the first two fish though now there are about 10 of them, disappeared from the spotted tetra and then appeared on almost all 7 of my tetras.
Shouldn't the quick cure been preventing this? The temp was raised to 88-90 within about 48 hours maybe less of when I noticed the spots. It was that high before the spots disappeared from the first two fish. I kinda thought with the heat AND meds that the ich wouldn't be able to multiply but it appears to be doing so. Am I misunderstanding the life cycle? Or did I just get a particularly evil strain? Should I switch meds? Or add salt? are the lights supposed to be off?
I have 2 GBR, 7 pristella tetras and 2 guppies. I have a penguin 200 filter going(carbon removed)
Any help would be appreciated!!
