蓝曼龙鱼（LanMan arowana）

蓝曼龙鱼（LanMan arowana） 蓝曼龙鱼(LanMan arowana) Bait fish, water earthworm, etc. Breeding water temperature 26-27 ?. The males are brightly colored, the tip of the tip of the dorsal fin is long and the female is pale. It is a foam egg. Females lay eggs of 500 to 1000 each time, between 10 and 12 days. Parental mature age 6 months. Mild temperament, can be mixed with other fish. When the water is deprived of oxygen, the water can be directly exposed to the water. Edit this paragraph Blue manlong, aka blue line finned fish. Distributed in Malay peninsula, Thailand, Indonesia. Features: 10 to 15 cm in length. Body shape is oval, body color blue gray, the body surface is full of dark blue pattern, the body color of young fish sky blue is very beautiful. Habit: the fish's pelvic fin has degenerated into a filament, so it is known as a silken perch. There are three extremely bright black spots on the side of the body, and one in the center of the trunk, one in the middle of the trunk, and the fish body is very pretty. The three round spots are like three black stars embedded in the blue sky, so they are praised as "samsung fish" or "blue samsung". First published in 1896 by the German J.F.U mlauff, the English name is Bluegourami or Threespotgourami (samsung Latin America). The fish farmers in southeast Asia, known as the "Bluesampan" (because of their size and the average "sampan fish", are just different colors). Other Chinese names include the dragon fish, the blue manlong, the black-spotted fin fish and so on. Blue (blue) manlong, also known as the blue star fish, is known as the Trichogastertrichopterus, which is known in Taiwan as the silkfin hairy fish and is affiliated to Anabantidae. Native to southeast Asia, Malaysia, Sumatra, Thailand, southern Vietnam, and India in South Asia. The fish's pelvic fins have been degenerated into filament, so it is also known as the silk foot perch. There are three extremely bright black spots on its sides, one in the center of the trunk and one in the base of the tail, which is very pretty. The three round spots are like three black stars embedded in the blue sky, so they are praised as "samsung fish" or "blue samsung". First published in 1896 by the German J.F.U mlauff, the English name is Bluegourami or Threespotgourami (samsung Latin America). The southeast Asian fish farmers called it "Bluesampan" (because its size is similar to that of "sampan fish", but only in color). Other Chinese names include the dragon fish, the blue bandung, the black-spotted fin fish, etc. Blue manlong depends on body color to distinguish, can be divided into two kinds: one kind of body color compares purple and red, the other is light blue. Dr Lodiges found that species from Sumatra, side no dark spots, so it is also called the fish Trichogastertrichopterussumatranus (blue foot perch, blue line fin fish). Edit the feature of this section The body is elliptical, lateral, the head medium large, the eye is big, located in the center of the head, the thoracic abdomen to the end of the tail end of the long arc. The pectoral pectoral position has degenerated into the end of silk da and the tactile ramandragon fish The role of organs. The adult fish is about 10 to 15 cm long. Its perfect for blue gray, the abdomen is light yellow, under the irradiation of weak light body beautiful and colorful violet, the body side there are three black spots, dorsal and anal fin and tail fin gray, white pearl spots on the fins. The dorsal fin is short and tall, with a yellowish color, and spreads like a small flag. The anal fin is long and extends from the chest to the base of the caudal fin, pale yellow, with a bright orange and red edge, and a soft skirt around the edge of the skirt. The caudal fin is shallow * and the base color is light yellow and transparent. The gill cover shimmered blue and blue. The body features of the lanman longfish: the length of the body of the lanmandragon is 10-12CM, oval-shaped. Sky blue; LanMan dragon fish breeding methods: raising water temperature 22-27 ?, the water quality requirement is not high. Bait fish, water earthworm, etc. When the water is deprived of oxygen, it can be exposed to the surface of the water. LanMan dragon fish breeding methods: LanMan dragon fish breeding water temperature of 26-27 ?. Six months later, the male is sexually mature, and the males are brightly colored. The tip of the dorsal fin is long and the female fish is pale. It is a foam egg. Females lay eggs of 500 to 1000 grains at a time, between 10 and 12 days. The temperament of the blueman dragonfish: mild in nature and mixed with other fish. Edit this ecological habit The requirement for dissolved oxygen The laminosaurus and lili and pearl fish have the same crimps as auxiliary breathing organs, located above the branchial cavity, and the mucosa ramanosaurus The complex folds of the shape can live in water with less oxygen and float to the surface to swallow air when the water is hypoxic, so they don't have to worry about the lack of oxygen in the water. Temperature requirements The fish likes to inhabit natural water areas that are not very mobile or completely static, and there is no special requirement for water quality. Need water temperature is higher, but the low temperature resistant capability is strong, sometimes occasionally at low temperature (14 ?), the minimum temperature of 11.5 ?. General breeding the fish is the most appropriate water temperature is 23 ~ 26 ?. diets It is an omnivorous fish which can be used for various living bait such as mosquito larvae, thread worms, water earthworms and water fleas. Also eat artificial bait, even eat live small fry, even shrimp crab seeds are feeding, but won't chase the small fish. But the blue star fish is the most popular feed on the surface. breeding Due to large trichogaster trichopterus body, and love quiet, so the aquarium should be bigger, the best planting some aquatic plants in the oven at the same time, if you can at the same time with beautiful stones into a rockery, both for blue star fish hiding, and can cause "to view line fish". The lanmandragon is adaptable, gentle and regularly swims to the surface. Because of its smaller than they are often bullied the fish, so can't and individual special small fish such as lotus lantern, traffic lights, green lotus lamp in the same collection of aquatic animals box, but it can be same as the size of other species of tropical fish collection. Edit this paragraph to identify gender Before reaching sexual maturity, the male and female characteristics were not obvious, and the gender was more difficult to distinguish, and the comparison was made by careful observation: (1) body color: the male fish had a bright color and the color of the blue mannana The female fish is dark; (2) dorsal fin and ventral fin: males have larger dorsal fins and apex of dorsal fin and anal fin, while females have smaller dorsal fin, and their dorsal fin and anal fin are relatively blunt. (3) abdomen: male fish abdomen is not full, while female fish abdomen is more full; (4) filamentous pectoral fin: the male fish filamentous pectoral fin is obviously orange and red, while the female fish filamentous pectoral fin is not obvious orange. When frightened, the male and female fish will show irregular sloping stripes. Edit the reproduction preparation work Only choose Trichogaster trichopterus generally after 6 ~ 7 months of growth can reach sexual maturity, had better choose length 10 centimeters or so, aged between 12 ~ 20 months of fish as a mother, so when the most fertile (months too big fish breeding is not ideal). At the same time, it is necessary to select the healthy, disease-free and bright color, and the male individual must be more than the female Fish are large, and females must have an obvious bulge in their abdomen, otherwise breeding may not be successful. Breeding tank The breeding tank should be large, and the specification can be 50 x 35 x 35 cm. The water temperature is slightly higher than usual 1 ~ 2 ?, with 26 ~ 28 ? advisable, the pH of the water is 6.8 ~ 7.2, the hardness of water is 120 ~ 150 PPM. It is important to keep the environment quiet and not to use the filter equipment. The rest of the arrangement and conditions are the same as fish aquarium tanks. After a careful selection of the females, the male = 1:1 ratio of the male to the breeding box, the preparation activity that begins spawning, the male fish has the behavior of nesting. Feeling and nesting When the males find the right place in the breeding tank, they begin to float to the surface, swallow air, and build floating foam fish nests. Because the blue star fish has the habit of building a foam-floating nest before laying eggs, it is best to put some floating waterweeds on the water, or a piece of plastic foam to make its nest easier. Its foaming nest is relatively large and relaxed (a diameter is 5 ~ 15 cm), Relaxation is because its nest often does not contain miscellaneous branches or broken leaves. During the male nesting process, the females are usually motionless, but occasionally they swim near the foam nest, which seems to be encouraging. Edit this section breeding and breeding Mating and birth After the nesting is completed, the males begin to chase the females. At this time, the fish, especially the male fish, change quickly, often from brilliant blue to dark green in a matter of seconds. If disturbed, it will immediately revert to the usual blue tone. The male will be in convulsion at the moment, wooing the female with various dance moves, and luring the female to blueman Into the bubble nest, perform production work together, the male fish curved body hug females, male and female fish body is bent into a "C" shape, the male fish head touch females abdomen, after both fierce hug back several times, the female fish egg to float nest spot excited male fish after ejaculation, fertilize the eggs. The fertilized egg white and transparent, the granule suspended in a foam fish nest. The male and female fish are so rolling and spawning that they repeat several times (7 to 10 times) for about 1 ~ 2 hours and the females are able to empty all of their eggs. Blue manlong is a large tropical ornamental fish, and it is a prolific fish, spawning a large number of eggs. Females can lay eggs of 800 ~ 1200 particles each time. Therefore, it is not expensive in the fish. To protect the egg When the female lays her eggs, she will free her nest and hide in the breeding box. She will rest in the hiding place and not swim. The male has the habit of taking care of the eggs, allowing them to stay in a breeding tank to protect their eggs. When I see the fertilized egg fall from the floating nest, the male catches it carefully with his mouth and throws it back into the nest. Female fish swim near the fish nest, and the male will also drive away, not allowing the female to approach the nest, and bite the female and even bite the female to death. Therefore, once the eggs have been laid, the females should be removed and raised immediately. seedling Appear on the second day after spawning, the fertilized egg eyespots, hatched larvae on the third day, newly hatched larvae of body color crystal clear, swimming organs has not been fully developed, not free swimming ability, can only be attached to the foam inside the nest, the body with oil the yolk sac of the ball for a. The fourth day the ball disappeared, and the fifth day the fish swam under the water. Due to the larvae of the individual is only 0.4 cm trichogaster trichopterus, much smaller than other tropical fish (0.7 cm), open food impaction hello HuiShui first, best first week supply ciliates with egg yolks, second week supply ciliate, fairy shrimp nauplius and little water fleas. If there are too many young fish, it can be raised in boxes. Daily management During the piglet, due to the immature gills of lanmanlong, or because of the high individual density in the cultivation of water, it is easy to be hypoxic and can be slightly inflated. In a week when the oil ball disappears and starts to swim in the water, the water will not be added, and the water will not be changed. Add a little water a week later. When silver long 12 ~ 17 days, to be very careful breeding, because at this time, the accessory breathing organs of impaction is beginning to grow, such as encounter cold air assault on the water, will suffer from "pneumonia" disease and death. In short, the death rate of small fish is very high at this time, but in the genus, the small fish of the blue star fish are very strong, and belong to the tropical ornamental fish that are easy to breed. Edit this section to raise The fish are known as Betta, ParadiseFish, KissingGourami, pearllgourami and three ramanon ThreeSpotGourami, BlueGourami, MarbleGourami, SilverGourami, DwarfGourami, HoneyDwarfGourami, coffee craft fish (chocolategou-rami), etc. In addition to the Thai doufish and the paradise fish produced in south China, the fish can be kept in the same fish tank before spawning. But when laying eggs, you should have another fish tank. The males begin to woo the females after the fish bubbles up in the water, blowing the air into the water. If the females are not mature enough to lay eggs, they will be killed by the male. When the tail ends, the male bends and encircle the female's body and then lays her eggs in the abdomen. The males ejaculate within the first time. Stand out the male fish and blow the egg into the bubble nest carefully to protect, until the young fish are born foraging. So, when it comes to spawning, you have to prepare another fish tank. Fish tanks don't have to be big. About 40 centimeters long. In the part of the aquatic plants in an aquarium, keep water temperature at 25 to 28 ?. Put the fish in first, and then the next day, the female fish. When the female enters the tank, the male begins to inhale through the surface of the water and sink into the water. In about half a day, the nest is created and the preparation for laying eggs is basically complete. Then the males and females begin to mate, and if the females do not cooperate, they can replace the fish. After mating, the females begin to lay eggs. After spawning, the male will watch the floating nest carefully and continue to spit out the foam to protect the nest. If the fish is out of the nest, the male will immediately return the egg to the bubble nest. About two days later, the young fish hatched. The young fish can't swim and stay in the floating nest, which can be maintained by absorbing nutrients in the egg umbilical sac. After two or four days, you can dip the egg into the water to feed the small fish. After three weeks, it can be changed to small water fleas or other animal feed, and can gradually raise the feeding amount, soon, the small fish grow up! Feeding features: moderate, but with other varieties of fish collection, is lax to water quality requirement, feed water temperature is 22 ~ 24 ?. The bait is mainly small and active food, and the food is more complex, and the artificial feed can also be eaten well. Reproductive characteristics: young fish mature after 6 months. The male fish has the marriage color in the breeding, the characteristic dark blue, the dorsal fin, the end tip of the anal fin; LanMan arowana Female fish has lighter body color and swollen abdomen. Breeding 26 ~ 28 ? water temperature, water quality of neutral. In 60 x40x40 (cm) above the aquatic animals box placed in a number of floating grass, male fish spit bubble nest, then chase females lay eggs, the male fish use fertilized eggs hatch out into the bubble, the female fish eggs every 500 ~ 1000, after the spawning scoop out females, male left to take care of the fish eggs, 2 days later after being larvae hatched, the male fish catch. In addition, the variation of the blue manlong is jin manlong, the body color gold, the body watch has the pale yellow color pattern, the breeding and breeding characteristics are with the blue manlong. To say that he is an easy-to-use breed, I think first of all, two basic characteristics, one is good breeding, the other is the right price, if there is a third point to say his ornamental. Said his easy breeding, trichogaster trichopterus belongs to selectively, this subject fish have assisted respiratory organs, not lack of oxygen, the survival environment requirement is not high, the general water quality can survive, more important is that he is not picky, usually eat feed and from pellet feed to worms, almost as long as can eat eat. From temperature Angle for he is the strongest tolerance in ornamental fish, up to 30 degrees, heel to 15 degrees can survive, but should pay attention to what I use is to survive, the most appropriate or 22-24 ?. Besides price, blue manlong in the general place price will be in 10 yuan inside, the price is appropriate, everybody can accept commonly. Said big appreciation nature is needless to say, the first big attraction is his peculiar shape, pianpian is very interesting, the second is his color, blue, is also a bright spot in the ornamental fish, more three stripes adorned among them. The third one was his silk feet, and their pelvic fins were filamentous, as if they were hands, and were very clever, and very interesting. If there is one fourth place to look at, it is the fight between males. This is the common feature of douyu. It is also interesting to find two fighting together. Edit this paragraph Bluestar belongs to egg-laying fish fish, as ornamental fish species, its variant called Cosbygourami fin fish (blue line) and its biological characteristics have been relatively stable, shape characteristics similar to trichogaster trichopterus, different is the whole body strewn with marble light blue stripes, side there is no round black spots, There are only a few irregular black markings, often present at the rear end of the pectoral fin to the tailstock, but the latter two round black spots are more obvious. In the breeding of intensive methods, the black spots on the blue dragon body will gradually fade or become less obvious. Edit the disease prevention and control White spot Symptoms: the sick fish has a dull look, often itching in the water or in the rocks. The body surface is covered with white or light gray spots, and the sick fish have an interaction infection and two blue mandragon-fish Dye. There are two common pathogens: one is the small melon worm, which is similar to the fresh water, and the body surface of the diseased fish is white. One is the ovum flagellate, the disease fish surface is a light gray spot, not easy to cure. Method of prevention and cure: (1) will catch up to 30 ?, water temperature parasites will its cyst rupture caused by the water temperature rise, automatic out of the fish body, this kind of method of primary infection of white spot disease fish treatment effect is good, but the fish of the secondary infection disease effect is not obvious, must use drugs at the same time of baptism. (2) the new brick in urine soaking for 24 hours, after air into the tank, more than 10 hours after the white dots on the expansion of fish, again for more than 10 hours, the visible surface of the white dots are off, the effect is better. (3) the sick fish in fresh water, it consists of 9 1 copy of freshwater and seawater against the mineral formation, soaking time of 0.5 seconds - 2 minutes, should pay attention to watch the fish to adapt to the extent, see fish breath should move immediately when sea water. Put 10 kg of seawater into a glass tank, add 0.05 grams of copper sulfate, oxygenate, and soak the sick fish for 5-8 minutes, and then the surface of the body will fall off after 24 hours. The effect of this method on the first sick fish was better, but the effect of the fish was not obvious. Bad fins rot skin Symptoms: the disease is incomplete, the scales fall off, the skin is decayed and there are superficial ulcers. The cause may be the seawater ornamental fish with each other Compete for territory and fight each other, or doesn't adapt to the new water, cause skin injury, fin ray bow J bacterial interaction infection, especially in existing fish tank into the new fish, are more likely to appear this kind of circumstance. Control method: 1. 1 in 10 kg of seawater, cef2 or furazolone 4-5 tablets, leaching fish for 10 to 15 minutes. In 10 kilograms of seawater, release 0.2 grams of potassium permanganate, leaching fish for 5-10 minutes. Rotten gill disease Symptoms: the gills of the infected fish's gills are decayed with blood, and the gills fester, the gill cartilage is exposed, and the sick fish have difficulty breathing. Control method: 1. In 10 kilograms of seawater, add 0.2k furan xilin, leach 5-10 minutes. In 9 portions of fresh water mixed with 1 part seawater, leaching fish 1-2 minutes. In 10 kilograms of seawater, add 0.05 grams of copper sulfate, leaching fish 5-10 minutes.
