About
The Himedaka (literally 'princess medaka') is one of the oldest cultivated medaka varieties, with records of orange-coloured medaka kept as ornamental fish in Japan dating back to the early Edo period. Its warm orange body is a result of selective breeding for xanthophore pigment intensity. It is identical in care to wild-type O. latipes and equally robust.
