Medakas are elegant small fish, but they are pretty aggressive in the spring. Two male Medakas stare at each other with their tails bent, and the next moment they attack with a splash. After the queen-like female (who lived for more than five years) laid her last egg and died, many baby Medakas were born in the summer. *The life span of Medaka is usually about 2-3 years.
