Paradise-fish (Macropodus viridi-auratus), a Chinese species of Macropod often kept in aquaria for its beauty of form and colouring. In the male the colours increase in brilliancy at the pairing-season, and he swims around his wished-for mate, fluttering the long, delicate filaments of the ventral fins, or erecting those of the tail fin like a peacock's train in miniature.
