I've been reading up on treating ich, which has appeared on only one fish in my tank.
Do you all agree with the recommendation in this article for treatment lasting 4 to 6 weeks?

If I have a 77g display tank, what size QT tank should I be using if the fish is about 2 inches long? My regular QT tang of 10g, isn't going to be appropriate for this procedure. I'm thinking 20g perhaps?
