On the breeding and breeding of Cherry Fish

Cherry fish (BarbustitteyaBeraniyagala), which belongs to the family Cyprinidae. Bayako (Barbinae). Because its basic color is rose red, it is called red rose fish, and because of the marriage color of male fish in estrus, it is as bright as cherry blossoms, and there are cherry crucian carp and cherries? And so on. The English names are Cherrybarb and Crimsoncarplet.

Cherry fish is a small tropical fish native to Sri Lanka. The fish is small and colorful. Except for the jagged gold thread between the side lines, the whole body is cherry red. If the aquatic plants in the aquarium are properly arranged, coupled with appropriate lighting, the color of the fish is particularly attractive, showing a light brown color with health and environmental factors, and sometimes turning peach green; if the breeding environment is not good, the body color is more insipid. There is a wide irregular stripe of gold and black in the middle of both sides of the body, which passes through the eyes from the end of the kiss to the tail stalk, and there is another jagged golden stripe from the orbit, which is interlaced with the black stripes below to the tail stalk. The back above the above two longitudinal lines is darker and reddish brown. All fins are red. The orbital iris is silvery white and can emit a pearl-like splendor.

The male and female characteristics of cherry fish are obvious, and the body color of male fish is relatively bright, especially in the breeding period. When the male fish is in estrus, its body color is cherry red, which is very eye-catching, and the longitudinal band on the body often fades, while the female fish always maintains the primary color, the brown longitudinal band on the body remains the same, the body is fat and the abdomen is enlarged.

Feeding methods

In the natural environment, cherry fish live in the shade of rivers or streams; they are raised in aquariums for fear of being frightened, and they hide timidly when the sound is too loud. Therefore, it is best to plant some aquatic plants in the aquarium so that they have a place to hide and avoid being frightened.

In healthy and normal conditions, cherry fish are lively, love to chase and jump, and sometimes jump out of the water. In order to prevent the fish from jumping out of the box, the aquarium should have enough space for the fish to swim and play, and the box should be covered.

Males are competitive, but they don't fight. When two males and females are put together, the males will rotate to enhance their marriage color, compete for wonder, and show off their gorgeous colors in order to win the favor of the females.

Cherry fish swim quickly, are afraid of strong light, and often move in the middle and lower layers of aquatic plants, so the light of the aquarium should be kept weak, and some aquatic plants should be planted to reduce the strong light. They have strong adaptability to the environment and can tolerate low dissolved oxygen, and grow well in the water temperature of 22-30 ℃, and the optimum water temperature is 23-25 ℃.

Feed mainly on small zooplankton. Its mouth is as small as a cherry and is not good at fighting for food, so small bait should be taken when feeding, especially in the juvenile fish stage, it is appropriate to feed the artificially cultivated special bait "migratory water" (containing high density of fine plankton, including sand beetles, paramecium, etc.) for a long time each time.

Methods of reproduction

Cherry fish is an egg-laying fish, because of its small size, less eggs are laid, and the survival rate of hatched juveniles is low, especially in the first week due to water temperature, lack of food and so on.

1. The choice of parent fish

Those with full length 4cm or above, good body shape, lively and healthy swimming, full belly of female fish and bright pink body color of male fish can be selected as parent fish.

2. Preparation before reproduction

The aquarium for breeding should be washed in advance and some soft and small aquatic plants, such as foxtail, golden grass or duckweed, should be planted so that the eggs can adhere to the leaves and roots of the aquatic plants. Male and female pairing has to go through a process of adapting to each other, and even cherry fish growing up in the same aquarium bite each other when they are paired in the same breeding aquarium. A glass partition can be placed in the breeding aquarium, and the male and female can be raised separately. After getting to know each other, the partition can be removed to allow parent fish to mate.

The size of the breeding aquarium is 60 × 20 × 20cm, the hardness of the water is 79.0 degrees, the pH is 6.66.8, the water temperature is kept at 25,27 ℃, and the aquarium is placed in a dark place.

3. Spawning

After everything is arranged, the carefully selected parent fish will be put into the breeding aquarium at 1:1 in the evening. Estrus male parent fish will appear more red than usual marriage color, excited and active, chasing and playing, often make the water splash, and even jump out of the water. What are the breeding habits of cherry fish and others? Like fish, usually after a period of chase in a dark environment, parent fish begin to spawn and ejaculate side by side. The specific gravity of fertilized eggs is slightly larger than that of water and adheres to aquatic plants during sinking.

Parent fish have the habit of swallowing eggs after spawning, so as soon as mating is found, close attention should be paid to it. After each mating, feed a small amount of live bait to lure the parent fish as soon as possible to reduce the swallowing of the fish eggs; when the spawning and ovulation have stopped completely, the parent fish should be fished out in time. The female spawns about 50 to 200 eggs each time, and the number of hatched larvae is even less. During the spawning period, the interval between each spawning of parent fish is about 10 days.

4. Raising seedlings

At room temperature, the fertilized eggs hatched for about 24 hours, and the larvae hung their heads under the leaves or roots of aquatic plants for about 1 day, and began to swim and look for food on the third day. It began to be fed with "migratory water" and changed to small fish and insects 10 days later. Since then, as long as careful care, feeding, can be safe and rapid growth.
