About
Ulysses is a selectively bred medaka whose black-and-orange semi-transparent body carries fine, vividly blue lamé, with the sparkle shifting from blue to green as the light moves. Because its body color reacts to the container, the lamé contrast stands out most when viewed from above in a dark tub. It is hardy and easy to keep outdoors at roughly 15-28°C, breeds readily from spring to autumn, and develops richer color under sunlight; feed the small fry fine food frequently.
