Will shubunkin's breed with goldfish?
Shubunkin is just a fancy name given to a specifically coloured
Goldfish. Breeding one with a Golden coloured goldfish will result
in about 33% that look like a Shubunkin and 33% that look like a
Golden coloured goldfish and 33% that look like a mixture of the
two. The above results would only be accurate if the breeder fish
are properly line bred and their lineage is guaranteed. Otherwise
you could get anything from coloured goldfish to uncoloured
goldfish and a mixture of any kind of goldfish including Comets,
Fantails and Veiltails.
