How to care for a goldfish?
Who would have thought that the progenitor goldfish - the favorites of many aquarists - is ordinary carp, and even silver? With him, then the whole pedigree of goldfish began with all its varieties.
If you decide to purchase these pets forcontent in your aquarium, then you better choose a larger capacity. There is an opinion that an aquarium of classical round shape, opening from above or without a lid - "it's the most" for goldfish. But this is not so. It is recommended to use four- or six-shears with a cover, under which the lighting fixtures are attached.
therefore for the content of goldfish it is better to buy an aquarium with a capacity of at least 50 liters - they are easier to maintain biobalance. It can contain 6-8 fish if you provide your pets with continuous air purging and water depth will not exceed 30 cm. In an aquarium of 10 liters you can keep no more than two adult fish.
All kinds of goldfish like to dig in the ground at the bottom of the aquarium. So that the soil is not scattered in a chaotic order,use not very light materials - for example, a large pebble. In an aquarium with goldfish it is recommended to plant plants with stiff, large leaves and a good root system (for example, vallisneria, kubyshka, sagittaria, elodea).
Optimal for goldfish is water temperature 18-21 ° C. You can add salt to the water - for betterFeeling of fish - 5-7 g / l. It is advisable to regularly replace part of the water volume, especially if there are no appliances for aeration - then you need to replace 1/3 part, and the more often - the better.
Goldfish can rightly be called a glutton. They eat everything and in large quantities. Usually, they eat food of both vegetable and animal origin. There are ready-made feeds specifically for goldfish in the form of flakes and granules. They are good enough to use, because in addition to the necessary nutrients with a large proportion of carbohydrates, these foods are balanced and contain natural supplements that improve the color yellow, orange and red.
Remember that when feeding with dry food, anythey should be given in small portions several times a day. After all, they have a special feature when swallowed in the esophagus, the fish swell, increase significantly in size, cause constipation and impair the functions of the digestive organs. You can first hold the dry food for a while (10 seconds - flakes, 20-30 seconds - pellets) in water, and only then give them to the fish.
For a change in the diet of goldfish give and live food. Coretra, tubule, large bloodworm, rainworms - all this takes a few seconds. But remember that a goldfish should never be overfed. Do not throw her food more than she can eat in 3 minutes. A good time to determine the amount of food is the first feeding your pet. You just need to watch her and determine how much food she ate during these three minutes.
Sex differences in goldfish are weakly expressed, and to distinguish the male from the female is possible only duringspawning when the male has a "file" on the front rays of the pectoral fins and warts on the gill covers. Goldfishes are ready to reproduce after a year, but it is better to wait for their full development, maximum brightness and splendor of the fins - this is about the age of 2-4 years, and then breeding. Males begin to actively pursue females. At this time, they need to sit down and feed a variety of vitaminized foods.
