Description
The Atka Mackerel is a coldwater marine fish characterized by its striking vertical dark bands over a yellowish-green body. Native to the North Pacific, it is a predatory species that feeds on zooplankton, crustaceans, and small fish. Due to its large size and specific coldwater requirements, it is rarely kept in home aquariums and is primarily found in public aquariums.
