My three koi have names: Timothy, Wanda, and Sidekick (who grew into the biggest by far, of course). Only one of my 50 or so shubunkins/comets/regular goldfish has a name: Nixon, because the tail is crooked. None of the orfes do. Otherwise, only Fanny Fantail, who just lost her long battle with spawning-induced fungus. While it is sad that she died (and of course it had to be one of the few who got a name), she is responsible for the huge majority of the fish in the pond, so maybe she martyred herself to the cause of improved water quality to allow her offspring live happier lives.
