Breeders Specialising in Karasugoi Koi Fish:
Otsuka
Aokiya
Karasugoi koi, or “Karasu” for short, are renowned for their striking black physique which singles them out as one of the most elegant and understated koi types. Karasugoi’s body absorbs light instead of reflecting it, and has a stunning and dominant presence in any pond. Although a few Karasugoi showcase a subtle blue-black luster or slightly lighter belly, it is their defining characteristic to have deep, uniform sumi.
Their color lacks any distinguishable marks giving Karasugoi a unique yet mysterious feature that is seldom seen in a koi collection. Their bid to minimalism make them serve as a balance in the pond’s ecosystem while contrasting beautifully with the brightly patterned varieties of other koi with vibrant colors. Some hobbyists even regard this koi as a symbol of endurance.
At Fitz’s Fish Ponds, we proudly offer Karasugoi koi bred by respected names such as Otsuka and Aokiya. These breeders are known for producing Karasu with deep, even coloration, clean body lines, and strong growth potential. Whether you're building a collection or adding contrast to your pond, our Karasugoi koi offer dramatic elegance with a simple, powerful presence. Add one to your collection today!
