Shubunkin Fish





Shubunkins are similar to the common goldfish and comet goldfish in appearance.  They have streamlined bodies with well-developed and even fins. However, the Shubunkins are calico goldfish; they possess nacreous scales (an intermediate between metallic and transparent scales that are pearly in appearance). The overlapping patches of red, white, blue, grey and black (along with dark speckles) normally extend to the fins of Shubunkins. Blue is the most prized colour in Shubunkins.

Ease of care

Like any Goldfish, Shubunkin are extremely messy. This means that you will have to perform water changes and clean your tank more often that other species of fish. This is not too much of a problem, but can be time consuming.


The food we recommend is Goldfish flake or a Goldfish pellet.


The first thing to know about tank mates is that these fish are very active and will steal food from other fish. This means that slow moving or shy fish will not make the best tank mates.

Breeding / Sex

Shubunkin Goldfish were likely first bred in Japan from Carp and are now one of the 125 Goldfish species traded worldwide. They will breed in groups of at least 4 or 5. They are very sociable animals and prefer to shoal in larger groups. Shubunkin will spawn in the right conditions which means if you make sure the tank conditions are perfect, the fish will breed without any other intervention.

Life Span

With proper diet and water conditions, the average lifespan of a Shubunkin goldfish is around 10-15 years.
