As you may or may not recall, I have been fighting a battle against Ich in my 75g for about 4 weeks now. It was a losing battle. I lost all but 2 of my cardinal tetras. Strangely they were the only fish to be affected. The angelfish and the rainbow fish have never shown any sign of the parasite. The 2 cardinals that are left are not very happy just being a duo, and I have 5 threadfin rainbows in my QT who have been there for 4 weeks. During treatment, I raised the temp in the tank to 82 degrees and treated with Jungle Ick Guard. In my opinion, it was a useless medication, although maybe it protected the other fish. I don't know. I have read about and understand the life cycle of the parasite, and I know that you cannot kill it while it is on the fish, but only once it falls off and moves into the next phase of its life. When I started I had close to 20 cardinals and now only 2. So how do I move forward now? The remaining two cardinals are not showing any spots, and all the other fish are seemingly healthy. I want to get more cardinals (from a different source) and add the threadfins to the tank as well. Should I retreat with the Ick Guard, and then wait another week? How long should I wait to add fish? Is there anything else I should do before I add fish? This is a heavily planted tank, so I don't want to add a lot of salt if I can avoid it.
Thanks for your help.
