About
Tennyo no Mai crosses the Matsui long-fin trait onto a miyuki base so that the dorsal, caudal, anal and ventral fins all extend evenly, the tail spreading like a fan; the trailing fins, likened to a celestial maiden's robe, are its chief appeal. On a miyuki base the back tends toward a blue or white sheen, and colors range widely from strong scarlet to lamé-miyuki and albino. Care is outdoor-friendly at 15-28°C; the flowing fins show well from the side or above in a roomy tank. It can breed, but long-finned parents spawn poorly, so use younger fish, and avoid overcrowding since the long fins are easily nipped.
