This would be the support page in Koivet.com for the book “Keeping Goldfish” by Rick Hess, Fred Rosenzweig and Dr. Erik Johnson
And, in that text, is a link to the section of Koivet.com that will host the various updates and errata that may be in the pages of that book. That was many years ago.
However, should you actually land on this page from the pages of the old book, I’ll say “Hello there!”
As a reader of the book, ostensibly owner of a copy; if you need help, here you go: email@example.com
