Koi Types
Yamabuki Ogon
Yamabuki Ogons are a metallic yellow Koi. You don't want
to get a Yamabuki Ogon that is too yellow
when you are selecting one. For some
reason, they seem to develop Hi (red) spots, usually on
the head.
Yamabuki Ogons are usually popular with people that have under-filtered ponds,
because Yamabuki Ogons are easy to see in green water.

Hikarimono
Ogons are single colored metallic Koi. They come in a variety of colors
and variations. No Koi keeper's collection is complete without
at least
one or two Ogons in their pond.
