In case you missed it, I've got a growing Youtube channel with all my fish health videos and it's growing all the time. Doc Johnson's Youtube Channel for Koivet.com
Also, Koivet.com is being overhauled to a WordPress theme to be the best fish health, fish medicines symptoms and cure web site out there. Videos and pages melding into a comprehensive "course" to bring you up to speed with "what you should know" videos and pages.
Finally, I have my book on amazon.com which means if you have prime you can get Koi Health & Disease 2 overnighted in the event of an emergency.
