Last Updated: 2024/11/06, Also known as red lotus lights, neon lights, red light fish (Hyphessobryconinnesi), originally distributed in Peru, tributaries of the Amazon, Colombia, Brazil. Characteristic traffic lights are the more famous ornamental fish in tropical fish. The body length is 4 cm. She is delicate and small. The whole body is shrouded in turquoise brilliance, there is a bright turquoise belt from head to tail, and there is a red band under the turquoise belt at the back of the body. the belly is blue and white, red belt and blue belt throughout the body.

Also known as red lotus lights, neon lights, red light fish (Hyphessobryconinnesi), originally distributed in Peru, tributaries of the Amazon, Colombia, Brazil. Characteristic traffic lights are the more famous ornamental fish in tropical fish. The body length is 4 cm. She is delicate and small. The whole body is shrouded in turquoise brilliance, there is a bright turquoise belt from head to tail, and there is a red band under the turquoise belt at the back of the body. the belly is blue and white, red belt and blue belt throughout the body. In different light or in different environments, the color of the ribbon is sometimes dark and sometimes light.

Feeding characteristics

Gentle temperament, easy to feed, like to swim in groups in the middle and lower levels of the aquarium, can be mixed with other species of fish. The breeding water temperature is 22-24 degrees Celsius, the water quality is slightly acidic and soft water, and the water color is required to be clear and transparent. The bait is mainly small live food. He likes to live in an aquarium with dim light, and it is forbidden to shine in strong light. The water quality of daily feeding is mainly old water, and it is not suitable to add too much new water, otherwise it is easy to suffer from white spot disease.

Reproductive characteristics

The age of sexual maturity of parent fish is 10 months. It is difficult to distinguish between male and female. Generally speaking, the male fish is slender and the female fish is thicker. The bottom of the 30cm x 25cm x 25cm fish tank is covered with hair grass. The water is gentle and 26 degrees, and the water quality pH5.6~6.5, the regulator section should be carried out slowly, so that the parent fish have an adaptation process (or choose double distilled water with extremely soft water, adjust pH, oxygenate and set aside). A pair of parent fish were put in in the evening. The female usually hatched their larvae at dawn the next day, and the larvae swam for food 4-5 days later. The females hatched 200 eggs and 300 eggs at a time.

The reproduction of traffic lights is difficult, which is mainly manifested in the higher requirements of breeding water quality and the special nursing requirements of fish larvae. The water for reproduction needs to choose very soft distilled water, then adjust the water pH 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 envy bottle. Lay a layer of nylon mesh plate on the bottom of the large glass bottle (caliber 90mm, 180mm high, 130mm deep) (the mesh size should not allow the parent fish to pass through), and cover the net board with a little hair grass, put a pair of parent fish in each bottle. In order to increase production, 50,100 glass bottles are usually needed in the hatchery.

In the evening, put a pair of parent fish in a glass bottle and cover it with paper to create a dimly lit environment. It usually begins to lay eggs the next day and is observed at about 10:00 in the morning. The parent fish that have laid good eggs should be fished out immediately, and the parent fish that have not yet spawned can remain in the bottle, such as those that have not yet laid eggs on the third or fourth day. Parent fish should stop eating during spawning so as not to deteriorate the water quality. For bottles that have laid eggs, they should be concentrated in a corner, and a manual egg picking work should be carried out at 9: 10 p.m., all the unfertilized white eggs in the bottle will be sucked out with a straw, and the fertilized eggs will be hatched in a 30cm x 25cm x 25cm fish tank, and the water used in the incubator will be poured into the upper layer of the spawning bottle. As the breeding water of the traffic lights is slightly acidic and highly soft water, the old water must be used as the hatching water. Can not be replaced with new water. 400 eggs and 500 eggs are concentrated in each tank, and the larvae are hatched after 48 hours. The water temperature is always kept at 25 degrees. It is best to paste it with paper around the tank to avoid deformities caused by too strong light.

Because the larvae are small and swim less, the bait can only be eaten at the mouth. Open the bait, sift the egg yolk ash water with 200 mesh gear, feed it drop by drop with a straw, wait for a period of time, when the larvae swim normally, and then feed the egg yolk ash water screened by 150 mesh gear. Due to the slow growth of larvae, it takes longer to eat egg yolk ash water than other small species. In addition, the hatching water quality of larvae is very soft, and the water temperature is completely different from that of daily feeding. When the larvae grow to 5mm, feed the larvae together with the water in the 50 cm x 40 cm x 40 cm aquarium with the same water temperature, so that the larvae can slowly adapt to the quality of the daily water. At this time, the larvae can be fed to small fish and insects, and two tablets of oxytetracycline can be dissolved in the water to prevent bacterial infection. when the young fish have red and green color, they can be raised in a large aquarium with a length of 80 centimeters or 100 centimeters until they grow into adults.
