Breeding and breeding of traffic light fish

Morphological characteristics of traffic lights

Red and green light fish, also known as red lotus light fish, neon light fish, red and green neon light fish, red light fish, cyprinidae, native to the upper Amazon tributary of South America.

Traffic light fish is petite, only 3-4 cm long, but the body color is extremely gorgeous, there is the laudatory name of "queen" in tropical fish, it is one of the most popular tropical fish species. Above the side line of the fish, there is a blue band extending from the eyes to the tail handle, the back turns black later, and the lower anal fin is silvery white in front and bright red at the back. The eyes are black and the sockets are silver-blue with a black edge. The fins are colorless and transparent, while the dorsal fin, anal fin and caudal fin are decorated with red patterns. When swimming, the fish color flickers under different light refraction, which is even more dazzling.

Feeding requirements of traffic light fish

Traffic light fish are gentle and timid, like group swimming, are typical bottom fish, have high requirements for feeding environment, suitable water temperature for life is 22-24 degrees Celsius, water quality requires weak acid soft water (pH6.4-6.8C, hardness 4-8), feed water should keep old and clear, change water less, the environment should be quiet, avoid direct light, aquarium tank should plant some narrow-leaf water plants, and the bottom of the tank should be covered with dark substrate. Other bait is not very demanding, generally fresh bait and industrial bait can be fed. The life span of traffic light fish is only 2-3 years.

Male and female identification and reproduction of traffic light fish

The main methods to distinguish the male and female of the traffic light fish are as follows: the abdomen of the mature female is enlarged, while the male is narrow and thin. During the spawning period, the female is pregnant with eggs, the belly of the fish is fat and round, and the body shape of the male is the same.

The 6-month-old red light fish entered the sexual maturity stage, and the best breeding period was from 8 to 10 months old. Traffic light fish reproduction is more troublesome, the breeding tank needs to be covered with brown silk or plastic wire, water quality requirements pH5.6-6.5, hardness 1-3.5 soft water. The adjustment of pH value should be carried out slowly so that the fish have an adaptation process; the water for reproduction should be shelved for several days or distilled water with sufficient oxygen capacity should be used. Fish can be paired or reproduced in groups. At night, the breeding fish will be paired into the breeding tank, the temperature will be kept at 25-26 degrees Celsius, generally the next morning will spawn, each time can produce about 200. After spawning, the breeding fish will be taken out and raised separately, and after a few hours, the unfertilized white eggs will be sucked out. Generally, the larvae can be hatched after 36-48 hours of fertilization, and the larvae begin to swim in 4-5 days. At this time, only egg yolks or small water fleas can be fed. Special attention should be paid to no strong light, and only weak astigmatism is allowed so that the larvae can see and forage.

During breeding, attention should be paid to shading the breeding tank, which is the key to the success of reproduction.
