Red light fish originated in South America, bordering Brazil and Columbia, and tributaries of the upper Amazon River in Peru. In March 1936 a French aquarium fish breeding collector A pull thibaut (A, Rabaut) through the Amazon River upstream of the Leticia border South America Brazil and Columbia between the two countries (Leticia) and Kobita Battin A (Tabatinga) in the jungle, in the stream, the swamp the beautiful small fish. When the news of the traffic light fish was released, it was a hit among tropical fish lovers. A few months later, a group of live lights arrived in France and later shipped to the United States and germany. It is said that the first Americans to go to the United States have a very high price, and the market price is as high as $100 per pair. Previously, because of artificial breeding method is not

smart, all rely on import supply market demand, so the price is very high. Later, after the study by Makino Shinji, director of the Japanese tropical fish Research Institute, breeding was imitated everywhere, so the price became popular.

Two, feeding methods

In the natural environment, traffic light fish swarms incessantly in love quiet waters, when artificial feeding, this should be taken into account at the same time, it is best to raise dozens of fish, the aquarium layout is to create the origin of the environment, planting density is the water tank, and placed the rock, let the fish playing in the group between water and rock, side by side, look good, do not lose their ornamental value. Aquarium should not be placed in too bright, strong sunlight direct place, the bottom of the box should be dark dark tone is appropriate. The traffic light is timid, and the environment requires silence so that it can grow and develop well. Feeding the fish in the water, especially clean, fresh tap water should not be used, so they should often use a long time to reserve some water to prepare for possible period of want or need should pay more attention to juvenile fish, especially, otherwise prone to white spot disease.

The light fish loves to swim in the lower water,

Hi acidity (pH 5.6 to 6.8, hardness 4~8 degrees), soft water for old water, water temperature maintained at 21~24 degrees celsius. The bait is not demanding, fish and insects, earthworms and other fresh water feed and dry feed can be used

to feed.

Traffic light, fish sex docile, best single raise. Juvenile body is too small, not with large fish polyculture, its tail is red, and it is the red spider, red bug similar color, such as feeding and large fish together, even mild temperament of species, such as angelfish, will be mistaken for fish food and peck, the fish was fatal disaster. Of course, the adult red green fish can still be more docile and large fish in an aquarium in support.

Three, male and female identification

The fish are not easy to distinguish the female gender, slightly wider in the reproductive period of body fat, abdominal fullness, anal segment, body color is shallow; male slender body weight, abdomen is flat, the anal fin is small, sharp end, darker.

Four, breeding methods

Red green fish is oviparous fish, fecundity, spring and autumn every year, to thrive period, such as water temperature, water quality is suitable, the other seasons can only spawn reproduction, not much.

1., the choice of parent fish

The parent fish should be 3 cm long and 6 months old. The parent fish of 8~12 months is fertile, and the reproductive capacity is low for more than 2 years. Choose the activity of male mating.

2. preparation before reproduction

Red green fish breeding trouble, mainly in the breeding high quality, hardness, pH, water content of bacteria can be controlled in a certain range, the breeding time line intensity should be controlled, and the requirements of the special nursing larvae.

The breeding aquarium can be 30 x 25 x 25 cm in size, but very clean, should be put in the soft light, glare on the embryonic development of eggs laid on the bottom of the aquarium is not negative, but can spread to large sand, pebbles, chose Liu Shugen to a bunch of gold or grass, solitary thunbergii and weed a bundle, sink to the bottom in a glass fixed with thin, as a fertilized egg attachment. The egg attachment also acts as an isolating parent from feeding fertilized eggs. The water level of breeding aquarium should not be too high. Water should be injected into the air by water pump. The water temperature should be 1~2 degrees higher than usual, and it should be kept at 24~26 DEG C, so as to make the parent fish become hot. Water quality and ideal, to use deionized water, distilled water, and then use the pH adjustment to 5.6 sodium dihydrogen phosphate to 6.5, hardness is 1 ~ 3.5. To make its eggs, it is best to add a little salt to the water. If rainwater is used, it will need to be filtered and stored for a week or more.
