The scientific name for the Stickleback fish is Pungitius pungitus. It is a freshwater fish that can be found in Europe and Asia. The average size of a mature Stickleback is about 3 inches long, but they can grow up to 5 inches long. The body of the Stickleback is slender and elongated with a small head. They have two dorsal fins and their pelvic fins are located on their abdomen. Sticklebacks are also equipped with sharp spines that protrude from their back and sides. These spines can be used as a defense mechanism against predators or to catch prey.
The diet of a Stickleback consists mainly of insects and other small invertebrates. However, they will also consume algae and other plant matter if it is available. Foraging for food usually takes place during the daytime hours. When night falls, Sticklebacks will often hide among plants or rocks to avoid predators.
Mating season for Sticklebacks typically begins in late spring or early summer. During this time, male Sticklebacks will build nests out of plants and debris in order to attract females. Once a female enters the nest, she will lay her eggs inside before departing again. The male then takes care of the eggs until they hatch into fry (baby fish). After hatching, the fry remain in the nest for another week or so before venturing out on their own into the open water
