Koi Varieties – Butterfly Koi

Welcome to our newest blog in the ‘Koi Varieties’ series where today we will be looking at Butterfly koi. Often referred to as Longfin koi or, in Japan, Hirenaga (hee-REH-nah-GAH) koi, these fish are a little different to other varieties of koi as the term refers to a body shape, specifically in the fins and tail, of a koi rather than a specific colour and/or pattern.
