I like this site because it cites SCIENTIFIC studies from multiple sources. I don't mean to be rude, but "I read somewhere..." just doesn't cut it. Without backup in the form of sources/research, all it is is an opinion. I googled Marine Ich and couldn't find a single site agreeing with your 3 month hypothesis.

Are you on google scholar? I am not going to go back through the studies I looked at but if you go on RC and ask you will find someone I am sure who can point you to the exact one.

"I don't mean to be rude" but Take it or leave it...I don't care if it cuts it or not for you. Its a study that I believe was done a few years back and that was on of the findings. Think whatever you may, doesn't matter to me.

Actually here is one study about a new strain of ich showing how it can now survive in cold waters. It was found in Japan and is a great example of how adaptable this parasite (like any) can be.
