The upper part of the longitudinal band to the back changes from brown to black, and the lower part of the longitudinal band is silver-white in front of the anal fin. There is a bright red stripe extending from the center of the body to the caudal stalk. Under the refraction of light at different angles, the bright color bands on the body sometimes appear green and sometimes blue. When matched with the bright red stripes on the upper and lower body, it flashes red and green, and the anal fin is silvery white. The color match is just right. Especially in the water plant tank illuminated by the lights at night, dozens of traffic lights fish in groups, making the water plant tank more colorful, such as watching fireworks, very charming and very endearing.

Breeding environment of traffic light fish

It is not difficult to raise traffic light fish, but if you want to make the traffic light fish grow healthily, you also need to pay attention to certain feeding skills. The aquarium where the traffic light fish is raised should preferably be beautified with sinking wood and aquatic plants, and the water quality also needs to be stable.

Traffic light fish are gentle and easy to feed. It likes to swim in schools in the lower middle of the aquarium and can mix with other species of fish. The feed water temperature is 22-24 degrees Celsius, the water quality is slightly acidic soft water, and the water color is required to be clear and transparent. The bait is mainly small live food. It likes to live in dimly lit aquariums and exposure to bright light is prohibited. The water quality of daily water change is mainly old water, and it is not advisable to add too much new water; otherwise, it is easy to suffer from vitiligo.

Traffic light fish reproduction is difficult, which is mainly reflected in the high water quality requirements and special care requirements for juveniles. The feeding water needs to be very soft distilled water, and then adjust the pH value of the water to 5.6-6.5 with sodium dihydrogen phosphate, then inflate it with a larger air pump for 2-3 days, and pour it into a large glass bottle for use. Lay a layer of nylon mesh at the bottom of the large-mouth glass bottle (diameter 90mm, height 180mm, depth 130mm) (the mesh size cannot allow adult fish to pass through), then lay a bit of wool mesh board on it, and put a pair of adult fish in each bottle. To increase production, hatching chambers usually require 50 to 100 glass bottles.

Traffic light fish is very sensitive to water quality, and the most suitable temperature for raising is 24°C, weakly acidic water. When new fish enter the tank, at least 1/5 of the new water should be replaced to reduce mortality. After acclimatization to the tank, the old water and high oxygen environment should be maintained. A simple summary is: new fish use new water, old fish use old water. When new fish enter the fish tank, you need to add bactericidal drugs before each water change, such as gentamicin or cephalosporin, and no more than 4-6 fish tanks of 2000MM are enough.
