I posted earlier about my achilles have a bad case if ich. When I got home tonight he was still alive but looked even worse (if that is possible). I got him out of the tank filled my old aqua pod with some water from my tank and lowered the salinity a little to try to nurse him through this but it was too late he didn't make it.
I unfotunately have learned a very difficult lesson the hard way.
What I would like to know is if the rest of the fish show no signs of the *bleeping* parasite do they just have an "recession" so to speak? I have heard all too often that ich is always present in the tank no matter what you do. So my question is this. I have no problem buying a tank for QT for future additions but if it's true that ich is always present in the tank just not visibly so then what is keeping any fish from contracting ich after I quarantine it?
