Got back from supercon. I had a great time. We just set up a hospital tank for one of the angel fish. he has little things growing out of him everywhere. It isn't so cool. He's been moved into the bathroom in a bare 10 gallon tank on his own. We figure it is better not to stress the other fish with medication they don't need, not to mention if the parasites or whatever kill him, they shouldn't kill all the others. Or at least one can hope.
