Traffic light fish
The picture of traffic light fish swimming in schools is very popular among many aquarists. Good, because the traffic light fish is not difficult to raise and is gentle in nature. It likes to swim in groups in the middle and lower layers of the aquarium, so it is very popular among aquarium enthusiasts and is also a rare species in aquariums.
The traffic light fish is petite and slender, slightly flattened on the side, only 3 to 4 centimeters long. The head length is smaller than the body height. The muzzle is short, its length is smaller than the diameter of the eye. Mouth is small, sub-superior position. The eyes are large and located on the upper part of the head. The dorsal fin is located in the middle of the body, starting from the tip of the snout and less than the distance from the base of the caudal fin. There is an adipose fin, which grows above the caudal peduncle. The anal fin is longer and extends behind the caudal peduncle. Pectoral and pelvic fins normal. The caudal peduncle is longer than the caudal peduncle is high. The caudal fin is deep and well-shaped.
The traffic light fish has a bright and gorgeous body color, with an olive green back. The eyes are black, and the eye sockets are silver-blue with black edges, emitting a green light. Above the lateral line, extending from the eyes to the tail stalk, there is a light blue neon vertical band, which is bright and dazzling. The color changes from brown to black from the upper part to the back, and silvery white from the lower part to the anal fin. There is a bright red stripe from the center of the back of the body extending to the caudal peduncle. The translucent colorful strip on the body sometimes appears green and sometimes appears blue when the light is reflected at different angles. Matching the bright red stripes on the left and right sides of the body, the red and green are shining, and the anal fin is silver-white, making the complexion harmonious.
