Mike, I'm with you on the shiros. I don't think it has anything to do with luck. My sanke, yamabuki ogon, shusui, and my kujaku are all healthy. That shiro of mine just gets so stressed. I added two little 5 inchers into the pond and she automatically came down with a bacterial infection which lead to fin rot in one day!

I treat her and in no time she is back healthy as ever. Never losses her appetite though. I call her Godzilla because she is a monster and eats like Godzilla. I'll put a pic on here of her in awhile. See what you guys think of my troublesome child.
