Goldfish. Many people start their aquarium hobby with this fish. The aquarium at home can be reproduced just as easily as it can be nurtured. Besides nurturing and breeding, both the beauty and the income of the house are possible.
Gold Face in Natural Environment ::
Goldfish live mainly in ponds, ditches, lakes and rivers and canals with low flows, where aquatic plants are located. In the natural environment, predominantly plankton, benthos, plant and detritus are eaten. They lay eggs in submerged aquatic plants.
History: More than a thousand years ago, goldfish was first raised in aquariums in China. Later, biologists from different countries were able to develop goldfish of various varieties. Among those worth mentioning are - Comet, Phantel, Lion Head, Oranda, Pearl-Scale, Pompom, Raikin, Red Cap, Black Orenda, Subunkin, Telescope, Rancho, Panda, WheelTel, Butterflight.

Common gold fish
Goldfish are one of the most reared domestic fish in our country at present. It can be said that rearing these fish accustomed to artificial packet-type foods in the aquarium is very easy, so it is through this fish that the handsome fishery is reared.
Classification of Goldfish:
Class: Osteichthyes
Sub-Class: Actinopterygii
Order: Cypriniformes
Sub-Order: Cyprinoidei
Family: Cyprinidae
Genus: Carassius
Species: Carassius auratus
Breeding time, age and temperature:
Goldfish lays eggs anytime the temperature is favorable. Typically 5 degrees Fahrenheit temperature is required for their breeding. In the temperature of Bangladesh, the eggs from the end of March to September. Despite the heavy winter eggs, it is difficult to save the winter for the winter. Goldfish growth requires about 5 degrees Fahrenheit. Goldfish are suitable for breeding from one to two years of age.
Identification of female and male fish:
In the case of small fish, it is very difficult to identify the female and male fish, but it is easy to separate the female and male from the older fish.
2. The egg in the stomach is actually soft and swollen in the stomach of a female fish. On the other hand, in the case of male fish, stomach is stronger than female fish
2. The genital opening of the male fish is more white than the female fish.
3. The pectoral fin of the female is very soft but the pectoral fin of the men is rubbed.
3. Before the reproduction of the fish in the stomach, the genital opening of the sperm in the female fish and the male fish in the female fish. However, this process is harmful for both fish.
3. Also, by observing the behavior of these fish, it is very easy to separate the female and male fish. In an aquarium, you will need to release some fish with water. After a while the female fish will pursue the male fish. The female and male fish can be easily separated from this.
Aquarium preparation for breeding:
A pair of 5-6 inch gold fish can be easily bred to aquariums of 5 inches in width, 6 inches high and 25 inches in length.
It is best not to filter the aquariums that will be reproduced. The filter lifts the water from the bottom. In this case, when the eggs are hatched, the water will be pulled down to the bottom of the stone. The aerator can be arranged to meet the oxygen deficiency of water.
Both females and males eat the fertilized eggs. For this, both the female and male fish are kept separate from the egg. There are different methods for this. As-
When the marble is laid in the aquarium, the egg goes into the marble hole and remains safe.
Many use breeding mats for breeding. It is like carpet and is placed on the floor of the aquarium. Once the egg has been fertilized, the mate has to be picked up and placed in another aquarium. The new aquarium can be replanted by placing a new matt in that aquarium.
Also an easy way to keep the fish separate from the eggs is to use a breeding box. The breeding box is relatively easy to use and low cost. This requires a few net shopping bags and thicker ones. The mosquito net can also be used instead of a net shopping bag. First of all, a box shaped frame slightly smaller than the size of the aquarium must be made with it. Then you need to stick it around the frame using the net in the shopping bag of the net. The diameter became the breeding box.
The bottom of the breeding box should be placed at least 3-5 inches above the floor of the aquarium. In no case should the fish reach the floor of the aquarium and do not lay eggs.
Breeding:
After placing the breeding box in an aquarium, healthy, normal 2 males and 5 females should leave the fish in the breeding box at night. As a result, the fish eggs will come out of the breeding box and fall down. As a result, the fish can no longer hatch eggs.
Before leaving the fish, it is important to note that the temperature of the water in which the aquarium is served and the water temperature of the reproductive aquarium should be the same. After leaving the fish should be monitored constantly.
In a short time the male fish will chase the female fish and hit the head with various places in the body, especially the abdominis or abdomen. As a result, at one point, the wife will release the eggs at one stage, prompting her to release the eggs. Male fish that participate in reproduction will also release sperm almost immediately. As a result, the eggs of the goldfish are fertilized outside the body. Neither female nor male fish can be seen in parental care, but they eat the fertilized eggs. Therefore, both eggs should be removed immediately after the eggs are fertilized and methyl blue should be added to the water, which will reduce the risk of fungal attack on your eggs. After using the net breeding box, it should still be kept in the aquarium because the net also contains some fertilized eggs which can destroy the fish that are breeding.
Usually the eggs hatch within 3-5 hours.
During the breeding season, it is appropriate to remove the fish that are participating in the breeding season and feed it well in another aquarium and re-lay eggs within 3-5 days if taken care.
If there is one night in the breeding aquarium, even if the fish is not breeding, then the fish should be removed and re-fed to the breeding aquarium for a few days.
Number of eggs:
The number of eggs depends on the fish's age, shape, body health and regular care. The egg laying rate of older fish is comparatively lower than that of young fish. In the natural environment, the rate of laying of eggs of goldfish is 25-5 eggs per breeding. On the other hand, the rate of laying eggs in a controlled environment is 25 ৩০ 12.2 eggs per gonad or 1.5 eggs per gram of body weight.
According to the method presented in this article it is possible to get 8 to 20 pods of goldfish per breed.
Egg Care:
Many use methylene blue in egg aquariums. 3% methylene blue is enough to give 5 drops. Methylene blue darkens the water and protects the eggs from fungal invasion, inhibiting the growth of various parasites in the water.
Eggs must be kept away from excess temperature and light. If the light is high, the aquarium can be covered with a cloth during the day. However, the air should be as dense as possible and be careful not to get too dark.
Egg color:
The egg color of the goldfish is immediately translucent, after which the egg gradually becomes somewhat transparent white. If you do not care well in the initial state of the egg, the egg can not be understood. Over time, the color of the eggs that are wasted becomes black, and many times they are infected with fungi and form a coating around them.
Hatching:
Usually the eggs hatch within 3-5 days. Temperature takes less time depending on the temperature. After hatching, the pona lays on the walls of the aquarium for 2-3 days. It can be seen only with empty eyes.
Recipes:
If you have to spend 12 hours in the bloom then you have to feed. Because for the first 12 hours, the pona fish gets its nutrients from the rinse bag.
After 12 hours, only boiled Artemia and boiled egg yolks should be given as food (the amount of egg yolk should be given because egg yolks spoil the condition of water very quickly). In small cases the protein intake of food is higher. The big pony can be given tubewax. However, it is better to crush it. The fish should be fed twice a day (morning and afternoon).
In the next one and a half to two years, the podas grow and are suitable for breeding.
Which is a must:
Care must be taken to keep the female and male fish in a separate location.
Fish should be given regular nutritious food before and after breeding.
The open net cannot be used while making the breeding box. This will allow the fish to try to get out of the broken section and get injured. After laying eggs, the eggs will hatch.
The female and male fish need to be separated as soon as the eggs are fertilized.
