--- But names will never hurt me!" LOLs

well names may not hurt but they certainly can confuse us !!

I posted the article on Nomenclature so as to give the budding koi keeper a sense the sub-divisions that exist out that. Sub-divisions that break our hobby (and therefore both focus and commitment to details) into different hobbies. Hobbies that are just as different from one another as goldfish bowls are to tropical fish keeping and marine fish keeping.
In this conversion some of us got into the Japanese view on 'GOI'. I'll begin with a riddle:

ALL KOI ARE GOI
BUT NOT ALL GOI ARE KOI!!
CAN YOU TELL US WHY?

All 'koi' are common carp. But all common carp are not koi. And certainly all common carp are not Nishikigoi!

Our first ZNA chairman Kuroki San clarified this point some 40 plus years ago when he said ( paraphrase) that nishikigoi are a unique creation from Japan and that koi has become the short name for colored fancy carp and goi is the description of the magoi ( wild, feral or domesticated food magoi).
