About
The Tsugaru Nishiki is a regional goldfish variety nurtured in the Tsugaru region of Aomori Prefecture, one of the varieties representing the indigenous Japanese goldfish culture that developed in the Tohoku area. Characterized by nacreous (translucent) scales and a distinctive coloration, it has a history of being carefully handed down as part of local tradition. Although its numbers once fell sharply, it has been protected and passed on through the efforts of local enthusiasts and preservation groups—a precious goldfish of high historical and cultural value. Its appeal lies in the soft coloration showing through its translucent scales and the particular charm of a regional lineage. Maintaining the strain and shaping its body and color take knowledge and effort, so some experience is needed to raise it. House it in a tank of 60 liters or more with clean water; being omnivorous, feed mainly prepared foods supplemented with bloodworms or daphnia. Calm lighting and stable water show off the coloration unique to nacreous scales.
