I've been watching my nearest LFS closely for the last few months (there's always SOME reason to go in every few weeks...) and have noticed a cycle in the goldfish tanks. They start out as in the pics which I took today. Slowly you go in and the numbers diminish steadily, until at the end of the cycle a few sickly specimens are floating around with dropsy, dead, fin-rot and all the disease that you'd expect after extended periods in these conditions. The tropical fish NEVER die off like this. Anybody know why? They are kept in just as crowded, if not worse conditions.
