The Barramundi, also known as the Giant Perch is a fish that is rarely seen in aquaria, most likely due to their enormous adult size. Barramundi can grow well over a meter, and must be kept in very large aquariums. Depending on the diet of the fish, individuals can double their size for the first 6-12 months of their life. An interesting fact... All Barramundi are born as males. They begin their lives in freshwater, where they remain until they reach sexual maturity. At that stage, they migrate downstream to the mouth of the river system to join the females for spawning. The females are older fish which changed sex, from male to female, during one of the previous breeding seasons. The Barramundi spawn in saltwater and then some will return to the river (those that remain males) and others will remain in the ocean and become females.
