First, the name of the kissing fish and the origin of the kissing fish, also known as the kiss, its biological name is Helostoma temmincki, belonging to the family Helostomidae, Helostoma. Their common names include kisser fish, gourami, kiss fish, kiss fish, kissing betta, peach fish, and croaker (Taiwan). The English names include kissing gourami, kissing fish, pink kisser, and green kisser. Many tropical fish lovers commonly use Chinese-English name kiss (ing) fish.
Kissing fish are native to Java and Borneo in Thailand, Malaysia and Indonesia. This kind of fish likes to live in still waters. It is often distributed in irrigation canals in rice fields and rice fields. Under natural conditions, the kissing fish can grow to 30-40 cm in size and have food value. It is a fishery target in Southeast Asia.
Second, the ornamental value Kissing fish is one of the common tropical aquarium fish. In a narrow aquarium, the body length can only grow to about 15cm. Compared with other tropical fish, the kissing fish does not have a particularly bright and attractive color. It is also very common in appearance. But the ability to win favor with tropical fish lovers is mainly due to the peculiarities of their behavior.
There are many sucker-like teeth on the upper and lower jaws of the kissing fish. When the two fish face each other, they are as convenient as a long-distance lover. They extend their wide-mouthed lips and are trumpet-shaped. They kiss each other and kiss each other. Minutes or even tens of minutes. While kissing, they also have to swim and retreat to form a "one" shape. Sometimes the two fish do not form a straight line when they kiss, but they are "V" shaped or "human" shaped and can also maintain a long balance.
It has been observed that only two fish of similar size will kiss, otherwise this phenomenon is rare, and juveniles begin to “kiss†when they reach 3 months of age. According to relevant experts, the kissing of kissing fish not only occurs in the opposite sex, but also in the same sex. Actually, this behavior is neither the deep love between the opposite sex nor the friendly expression of the same sex. Some space possessed desire to drive and defend against their own "territory". This kind of inter-ethnic struggle appears to be relatively gentle, without bloody smashing, but "friendship first, match second". As long as one side retreats and the winner no longer pursues, there is a gentlemanly manner.
Kissing fish is also called "aquarium scavenger." In the aquarium, they use their foldable lips to look for tiny algae, moss, etc. on the stems and leaves of plants, on the walls or on the substrate. From time to time, the head is downside down, scraping algae; swimming head-to-head quickly and breathing air on the water surface with a large breathing apparatus. This movement is like a gymnast who does a vertical roll and is very attractive. . Raising the kissing fish in the aquarium makes it difficult for the microalgae to multiply, keeping the walls and bottoms clean, and making the plants more green and lovely. Therefore, keeping kissing fish is not only for viewing but also helps to raise other tropical fish.
Recently, people have cultivated a kissing fish that does not have a tail shank. It looks like its body resembles a peach. Its habit is no different from ordinary kissing fish.
Third, the morphological characteristics kissing fish in the aquarium usually only grow up to about 15 cm. Its shape is oblong and slightly flat. The head is large. The head occupies about two-fifths of the body length; the eyes are of medium size; the mouth is large, the mouth is cracked slightly, and the lips are developed and retractable; the lips are serrated; the kiss is blunt and the jaw is slightly longer than the upper jaw. There are two lateral lines broken, with a line between the back of the upper line and the line of the lower line. The dorsal fin originates above the posterior edge of the lid. The dorsal fins and anal fins have a long fin base that extends from the posterior edge of the lid to the base of the caudal fin, and is substantially symmetrically above and below. Pectoral fins are thick. The pelvic fins are short and located near the pectoral fins. The tail shank is short, and the middle of the tail fin is slightly concave.
Body color light cyan, milky white and pink three. Milky white is more common, pink is the most beautiful, and light blue is rare. Lips and eye mask are red, snout forward, slightly upturned; the head has black vertical stripes, black eyes are very eye-catching; caudal fins there are many inconspicuous black dots. Each fin is transparent and slightly pale in color. The abdomen is almost white, with black vertical stripes at the base of the caudal fin.
4. It is easy to raise the kissing fish in the aquarium and it grows extremely fast. They swim back and forth in the aquarium, seldom stay still; they often stop at the bottom of the aquarium during rest. Like a group of activities, and regularly floated to the surface to swallow the air.
Aquariums for kissing fish are generally not less than 40 cm30cm30cm in size. It can be raised individually, or mixed with more active tropical fish, but it cannot be mixed with small-sized fish such as traffic lights and blue-eyed light fish; it cannot be mixed with slow-moving fish such as colorful angelfish because of its lively nature. Kissing fish like to use a large mouth to shave the surface of these fish, affecting their growth. This kind of fish can be raised together with various large-scale ornamental fish such as Shark, and can also be raised with Arowana, and the colors are very beautiful. It must be pointed out that kissing fish cannot be placed in an aquarium with precious aquatic plants, otherwise most plants will be eaten.
Kissing fish grows well at a water temperature of 21 to 28°C. It is ideal for a water temperature of 23 to 26°C and a slightly acidic soft water. When the temperature of the water falls near the lethal temperature, the body of the fish becomes stiff and white. If the water temperature drops further, it will cause death.
They like to eat algae, but eating algae is just their active habits, in fact, the main food is still biased towards animals, like live leeches and other live baits. Because of the moss on the wall of the aquarium, it is susceptible to cotton mouth disease.
Five, male and female identification of male individuals is generally smaller than females, anal fins wider than females. In the breeding season, the fish body appeared marital color, and the body color of the male fish changed from pale flesh color to purple red and sparkled; the body color of the female fish also changed, but the purple color was less than that of the male fish. The female's abdomen appears swollen with large amounts of eggs. When males often swim alongside females, this is a sign of labor.
Sixth, preparation before reproduction In the case of adequate live bait, kissing fish after 8 months of feeding, body up to 8cm or more, the gonad has matured, but the reproductive success rate than the pearl vest fish, Lan Manlong etc. Lower.
1. Selection and cultivation of broodstock As a broodstock, individuals with a body length of 8 cm or more are selected. Even broodstocks with well-developed gonads may not be able to pair and reproduce smoothly, especially between males and females who are not familiar with each other and are stocked in the same pool. In order to increase the reproductive success rate, it is best to select more than 10 kissing fish with bright body color and well-proportioned body shape in the adult fish with a body length of 6-7 cm, and cultivate them in the same aquarium. Feed live baits such as leeches and otters, and feed them one month before spawning.
2. Breeding aquarium kissing fish requires little water quality when breeding, and prefers soft water quality, with a pH of 6.8 to 7.5, a hardness of 9 to 10, and a water temperature of 27 to 29°C (1 to 2°C above usual). Do not change the water frequently, otherwise it will incur illness and death. The breeding aquarium should be 100cm50cm50cm in size, because the number of larvae that can be bred can reach more than a thousand.
Kissing fish will devour the fish eggs they produce. Therefore, a layer of floating grass should be placed on the water surface of the breeding aquarium, or a thin net should be placed about 5cm below the water surface to isolate the broodstock so that it cannot be swallowed and float on the water surface. The egg.
3. In estrus when a male fishes a female, the female tends to remove the male from the beginning and does not let it go. Soon, the females accepted the males that were close to them and walked friendly along the wall of the aquarium along with the males. When this symptom of labor is found, the broodstock should be immediately transferred from the terrarium to the breeding box in a ratio of 1:1.
Seven, breeding and nursery
1. Mating and hatching Mating spawning is usually early morning or early evening. First, the males followed the females and gradually became fiercely chased. Finally, both swimed into the spacious aquatic plants in the center of the aquarium. The male and female fish twisted and twisted on the water, fighting fiercely on the water. Immediately after the female lays its eggs on the surface of the water, the males are then discharged and the eggs are fertilized. Normal males chase and wrap females around 10 times to produce eggs.
Kissing fish produce floating eggs, fertilized eggs float on the water. Since the fish will eat eggs after spawning, the broodstock should be fished out immediately after the spawning to avoid damaging the eggs.
The amount of eggs laid by females is generally between 1,000 and 3,000, and up to 5,000. Eggs are white, egg diameter 1.5 ~ 2mm. After a fertilized egg hatches for about 12 hours, the granules change from white to black (if a milky-white, opaque egg is found, that is, an unfertilized egg). Fish eggs contain a lot of oily substances and can easily grow aquatic fungi. Therefore, timely improvement of water quality is required. The eggs hatched larvae after two days and nights.
2. The newly hatched larvae are attached to the plants and aquarium walls. The body is gray and the yolk sac is large. After 1 to 2 days, the yolk sac absorbs and disappears and begins to swim. This time it is necessary to feed the paramecium, Rotifers, nauplii, and other open baits. After 7 days of ageing, small branches and copepods can be ingested. After another 1 to 2 days, the auxiliary respiratory organ, pupa, is also formed. Juveniles have the same appearance as adults and regularly rise to the surface to swallow air and start to scrape tiny algae from the plants, on the walls, and on the bottom. When the body length reaches 1.5cm or more, the fish worms can be gradually fed, and the cut otters can also be fed.
3. Juvenile fish grow up with the growth of juveniles, can be fed leeches and leeches. Kissing fish is not picky eaters, and it can grow well when it is fed dry feed. The broth to be fed is sterilized by rinsing and soaked in 15 mg/L potassium permanganate solution for 20 minutes. When feeding live baits, add some vegetables, such as lettuce leaves. Feeding dry feeds is prone to loss, and with the growth, increased food intake, excreta will also increase significantly. In order to maintain transparency and good water quality, it is necessary to divide the culture in time to reduce the density and use water filters.
After larvae have been reared for 2 weeks, they can be sieved and reared by individual size bins, otherwise individual size differences will increase. After about 30 days of feeding, the larvae grow and grow into adult fish.
