About
Goshiki is a two-tone black-and-orange medaka whose scales are outlined by a continuous, net-like 'black rim,' set boldly against scarlet-to-orange in the fins and flanks, which makes it a show favorite. Its key trait is almost no background reaction, so the deep color holds even in a white container, letting it be displayed anywhere. It is hardy, grows well outdoors at 15-28°C, and breeds easily in warmer months; sunlight sharpens the black-orange contrast. Derivative lines such as Type R, where scarlet reaches the head, are also well known.
