As the others have specified in the other post, it sounds like ammonia poisoning. Goldfish grow to be pretty big, and are very messy, and as such need a very big tank with a heavy duty filter to keep their water conditions tip top.

The only advice I can give echos what the others have said- keep doing water changes and try and get her to upgrade to a much larger tank! Small tanks are really no good at all for a lot of fish, and are never suitable if unfiltered and not de-chlorinated.

Tell your friend good luck, and keep us updated?
