Yellowfin bream is a marine fish of the family Sparidae and genus Acanthidae. It is generally 200 to 300 mm long, and the largest individual can reach 3.3 kg. The body is oblong, flattened laterally, narrow on the back, gradually inclined from the starting point of the dorsal fin to the tip of the snout, blunt on the ventral side, with a small curvature and a pointed snout. The mouth is medium-sized and almost horizontal, with the upper and lower jaws of approximately equal length, and the rear end of the upper jaw reaches below the front edge of the pupil. The edge of the preoperculum is smooth, and the rear edge of the operculum has a flat blunt spine. The gill sac is very short, about 6 times the diameter of the eye. The body is covered with thin weak ctenoid scales, and the head is covered with scales except for the interorbital septum, preoperculum and snout. The dorsal and anal fin spines have developed scale sheaths, the base of the fin rays is covered with scales, and the lateral line is complete and arc-shaped. The dorsal fin spines are strong, with the fourth or fifth fin spine being the longest, and the dorsal fin starts slightly in front of the base of the pelvic fin. The anal fin is opposite to the dorsal fin ray, and the second fin spine is significantly stronger. The living body is bluish-grey with yellowish color, and there are several gray longitudinal bands on the sides of the body, running along the scales. The dorsal fin, a small part of the anal fin and the edge of the caudal fin are gray-black, and the pelvic fin, most of the anal fin and the lower lobe of the caudal fin are yellow.

Different habits: The black swallowfish has a gentle temperament and elegant manners. It likes to swim in the middle layer of the water and often stays still in the water. It has a quiet habit and is best kept in a single tank. It has no strict requirements for water quality and prefers soft water with weak acidity. The yellow-winged fish lives in 1 to 50 meters of water. It often moves around oyster sheds, mangroves or wave-breaking blocks in estuary areas. It is a euryhaline fish.
