Each year, as the days lengthen in spring, mature goldfish begin the process of egg production in females and sperm in males. Many of these changes are caused increased daylight and warmer water temperatures. The availability of increased food production in the form of worms and mosquito larvae, whether colorful fish outdoors, in addition to changes in the fish.
The changes that occur in goldfish include generalized swelling in women, as the eggs begin to develop, and the appearance of small bumps or "tubercles" on the main edges of the pectoral fins, and covers gills in men.
In warmer climates, goldfish can begin spawning in the open air at the end of April, but in many other areas, fish color begin spawning in May or June. In many cases, fish eggs without apparent evidence, especially if the fish is kept in a pond, and a mixed population. To fish kept in aquariums, the signs are present if the fish are closely observed.
Spawning will take place early in the morning, usually just before sunrise. Spawning activity appears to be triggered by several factors, including: the rain in the days before spawning, a decrease in water temperature a few degrees, the water changes, and a full or almost full moon.
Spawning generally lasts several hours, and thousands to tens of thousands of eggs are laid in Depending on the size of the female. The eggs are usually fairly small, round and sticky. Please see the following picture of the eggs to make an indoor aquarium, to get an idea of the size and shape.Please remove adult fish after spawning, if you want to raise babies. Adult fish eat the eggs (and the Republic FRY) after spawning. Fry, once recognized, shall not be eaten by mature goldfish. Fish generally recognized once babies arriving ½ "to 1" in size.
The eggs usually hatch in 4 to 7 days depending on water temperature. The pups are very small at the time of hatching, and feed for the first 3 to 5 days in the yolk sac attached. At birth and for a period of approximately two weeks after hatching, the chicks will remain attached to the surface where the eggs were, or near the water surface. As its swim bladder starts working, the fry begin swimming at all levels of the aquarium.
After the Federal Republic of Yugoslavia have depleted their yolk sacs, you should start feeding them food. Principles of food may include: Newly hatched brine shrimp, egg yolk, and infusoria. For people who have an outdoor pool, feeding can supplement the diet of juveniles found in the pond. For people who have actually stayed in an aquarium fish, food will have to be supplied by the owner.
After a few weeks, crumbled flake foods, foods of little, collapsed freeze-dried blood worms, Daphnia, and brine shrimp can feed the fish. During the early development phase, feed the fish several times a day (maybe 3 to 5 times a day) in small quantities. It is important to carefully monitor water quality and to make periodic changes of water, such as certain foods (especially egg yolks) can foul the water.
Fish begin to de-metallic color, which is the wild green color change in 2 to 3 months of age. For fish pearlescent and matte colors tend to deepen the mature fish. More pearly fish and start with a color Matte white mottled with red, black, oranges, and blues in development as the age of fish.
If you are raising fry for breeding or show purposes, will have to select juveniles who possess the characteristics that you have provided in their breeding program. Fry with deformities such as missing fins, tails tripod (in the case of double-tailed varieties), and other physical defects can be transferred or removed from of 6 to 7 weeks. The practice of selection of fish with certain characteristics are known as "sacrifice".
A second sacrifice can occur in 8 to 10 weeks, and will focus on color and conformity to standards of race. A sacrifice of 3 can be done in 3 months, at which time most fish are starting to show special breed characteristics, including head growth, eye development, and the pearl scales. It is not uncommon that only 5 to 10% a spawn to stay after slaughter third. While some people object to the idea of giving away fish, or a sacrifice of spawning, goldfish will not thrive in more of overcrowding. The practice of reducing the size of the population is necessary for the development of goldfish and quality.
As fish approach 2 to 3 months of age, attempting to feed a higher percentage of dried live foods, frozen, or freeze. The increased protein content in food is necessary for development of head growth and the scales of pearls in particular. Avoid feeding floating foods, which, although good for koi, and not very useful for goldfish, in particular the full content of double fish tail. The continuous supply of food will cause floating goldfish to consume large amounts of air, and may alter the balance of fish. Sinking food pellets or granules can be fed for 2 -3 months, in addition to the live or frozen foods.
For those interested in the making their own food, food recipes from several goldfish are available, both online and GFSA (Goldfish Society of America) articles. Books such as The Goldfish Guide by Matsui also included homemade recipes.
The ultimate sacrifice can be achieved in six months, which is conducted to select the fish to grow and overwinter. This selection is based on a combination in accordance with standard guidelines, color and overall confirmation. At the end of killing 4, it is likely that only 1 to 2% of eggs will remain, and that fish selected to be exceptional.
