Ok, so this has to be more than a coincidence! My fish have gotten themselves Ich twice in the last year. Always on addition of new fish. The first time it was the Espei Rasboras, and this time it was the Cardinals. The ONLY thing I did to treat it was add 1 drop per 10 gallons of Kent Garlic Extreme. In both cases the Ich was cleared up within 36 hours, and I lost no fish. Has anyone else ever tried this?
