Fish Aficionado
To pipe in and agree with Miss Wiggle, the best LFS we have in the area always has quarantined fish. Usually it's because of the stress from shipping that causes it as I rarely ever see "old" fish in quarantine. It's just one of the dangers of shipping fish. The worst I've seen was when they had 10 or so tanks quarantined out of maybe 200. That was a big deal to me because it's so rare to see more than two or three sick tanks at any one time. And it's never anything worse than ich or the occasional finrot.
