The difference between the two types of fish is as follows:

Appearance characteristics: The body of the Balang fish is spindle-shaped, slightly flattened on the sides, with a green body, a gray-white abdomen, and 4 to 9 vertical spots on the sides of the body. Bands and spots are distributed between the lateral line and the base of the first dorsal fin, and are sparsely arranged and not continuous. The saury has an elongated and slender body, slightly flattened on the sides, and is dark silver-gray in color overall. There are 7 to 9 light blue vertical stripes on the sides of the body, and the abdomen is light yellow.

Dorsal fin length: The dorsal fin of the Balang fish is located in front of the anal fin, with the first soft spine and 27-36 soft rays. There are five small fin spines before the starting point of the dorsal fin of the saury, which is shorter than the spines of the saury, and the barbs are less toothed and arranged in a shallower shape.

Tail fin length: The tail fin of the Balang fish is deeply forked, with the upper and lower lobes equal in length. The saury's caudal fin has a convex front edge, a concave rear edge, and asymmetrical upper and lower lobes.

Life habits: Balang fish often inhabit reef bottom waters. The saury is a cold-water, highly migratory fish that usually inhabits relatively deep waters.

Food habits: Balang fish mainly feed on small fish. The saury is a carnivore and mainly feeds on anchovies, sardines, sharks, herring, etc.

Reproduction method: The reproduction method of Balang fish is oviparous. The reproduction method of saury is also oviparous.
