Description
The Japanese Horse Mackerel is a schooling, pelagic marine fish found in the temperate and subtropical waters of the Western Pacific. It is a predatory species, feeding on smaller fish, crustaceans, and cephalopods. Due to its large size, schooling behavior, and specific environmental needs, it is not suitable for typical home aquariums and is primarily seen in large public aquariums.
