Description
The Sakhalin Stickleback is a small, slender fish native to the fresh and brackish waters of Sakhalin Island and Hokkaido. It exhibits cryptic coloration, typically mottled brown or olive, allowing it to blend into its weedy habitats. Known for its territorial behavior, especially during breeding, it constructs elaborate nests and is best kept in a species-only aquarium.
