Or put another way—
What form of ‘communication’ is best? Since communication is a way to check out personal experience/observations. Some forms involve REALITY! Hands on experience. This is usually best I think but then again, in a vacuum of personal experience without outside feedback, or in the case of limited experience- maybe the club experience is better? Or at least the next level of ‘exposure’ to the hobby for the determined? You could even say that the club atmosphere protects the newbie from themselves! Their impulses and judgement may seem logical based on their limited experience but often is exactly the wrong thing to do- case in point- over medicating.
I did pick up on a statement that Elunned made- about many koi keepers are really isolated and are basically water garden center customers. That of course, is VERY true. But 99% of those people will pass through our hobby in an 18 month to 36 month time period. So we can hardly gauge the purpose, direction, educational level or health of the hobby by their experience. I prefer to think of those consumers as people who keep koi for a while- usually juvenile koi, until they die, but maybe not actual - koi keepers ( a more determined and focused ‘breed’, I think!)
So we move on to the Internet as a form of communication/education– convenient and plentiful! But unfortunately often wrong!

Says who? Says me, and most koi keepers who have been around the block a few times. Check it out– if you repeat something enough times on the internet it becomes ‘true’! EVERYDAY, I read something on one of the three boards I visit that definitely isn’t true. Some times it is an innocent just repeating something they heard on a water gardening board or some other off-the-beaten-path source. And often it is a misinterpretation of a truth read on another board and it gets mangled in transposition/transfer. And just as often, it is an opinion stated as fact- something I have to admit, I’ve been guilty of from time to time, in the heat of battle. So for me, the internet is a fun distraction from real life and often quite interesting, but far too inaccurate to risk your koi’s live’s on.
As far as koi appreciation goes, almost every thing in writing loses its nuance - and most koi appreciation is three dimensional in that it involves hands on exposure, perspective and subtleties. Very few ‘written words’ can compensate.
And finally my pet peeve on these boards is when the over night expert discusses ‘ how things are in Japan’ when you suddenly realize that they actually have never! This is a common ‘disease’ of dealers and wanta be experts. Its an amazing phenomena to read the written word presented with such authority by a person who is simply repeating what their dealer or a BB said about Japan or a Japanese breeder!! At that moment, the self hypnosis is so strong that I personally believe the writer actually believes ‘ they have been there and seen these things they write about’. Scary.
Funny story– a well known ‘ professional’ wrote reams about Japanese transport facilities and how koi are often mishandled. I read these things with astonishment as they didn’t jive with my observations of the last 14 years of visiting Japan, but did not respond as I would only make myself look bad by correcting a much loved public figure in our hobby. Some months later, I found myself sitting with this guy at a social event. He leaned over and asked me " hey, you’re a guy goes to Japan, is it true that these fish are gathered from all over Japan and put in small concrete holding tanks?" I realized the man did not have a clue and was likely thinking that the Japanese system was the same as the tropical fish shipping systems of Thailand and Hong Kong??? I explained how they were very different. He thanked me for the input but never corrected any of the information he had already put in print. How many ‘readers’ of the Internet think they have a picture of real Japan after reading the fiction that man put in print? Many I would guess. Many who have talked to many others and ‘lectured’ on the bb’s to others as to ‘how it is’. Disgraceful.
So what is the answer? I think I have it!? Decide what kind of koi keeper you really are. Based on how important your fish and your hobby are to you, you can decide how much you really want to know. If you are a ‘storm trooper’ type and want it all, like me and my friends do, you need ALL forms of education- personal experience, a club affiliation, a few mentors, a good experienced teacher, A great relationship with an established dealer, books, magazines and the Internet. If you are a casual koi keeper and like water gardening in general, this is all way too intense and you should simply rely on a local dealer for all your information- at least it will be consistent. As for the internet, at that level, take full advantage of the social side of the hobby and share pictures, landscaping and the cute things koi do. And as someone already said- get confirmation on all serious data such as medication levels.
