they were sold to us by an aquatic centre as Shubunkin so I think they are -
will go barbel spotting and report back :-)

LOL They tried to sell me a shubunkin named as a koi....I argued with the
salesman, and called for the store manager, who marked down the price when I
pointed out the mistake to him....It was still in the plastic bag from the
store getting it in shipment..and on the bag was written med size koi )
