What is a fish cage? This is a separate space where fry and young fish are moved. This is done in order to save him from death. Most phenotypes consume immature fry as food. If they are not isolated, all offspring will die.
Varieties of jigger
Traditionally, fish troughs are used before spawning. The couple is planted for this period and returned to the general aquarium after spawning. The fry remain in the hatcher until they grow up. Beginning aquarists like to use glass jars and other containers as separate aquariums for young animals. This is not always convenient. Moreover, if there are several phenotypes in the aquarium, the number of jars can reach a huge number. This is not always convenient, especially when it comes to a small room. It is much more convenient and cheaper to make a fish tank in a common aquarium. Here are three of the most popular types of nurseries:
Each of these models has its own characteristics, advantages and disadvantages. Consider them in detail.
Mesh models are budget types. For their manufacture, a rigid frame, polymer mesh, organic glass or similar materials are used. The design is attached with hooks or specialized holders to the wall of the main aquarium. The net-type fish cage, despite its low cost, has 2 serious drawbacks:
- cells accumulate leftover food and waste products of fish;
- sometimes adults enter the nursery and damage the fry.
This type of jig is only recommended when no other options are available.
Transparent models are more versatile and easier to keep clean. They are made using plastic, polymeric materials, organic glass. Such a fish tank can be attached both to the wall of the main aquarium and placed on the bottom. When installing, it is important to consider that the water level in the tank must be below the level of its sides.
Combination Fish Depot combines budget price and easy maintenance. Installation requirements are the same as for transparent models.
Jigger for viviparous fish
Cultivation of viviparous fish is a special art. Aquarists go to many tricks to protect offspring from their parents. Traditionally, shortly before giving birth, the femaleplanted in a separate aquarium. After the offspring is born, she returns to her usual habitat. But there are some problems with traditional types of fry tanks. Minimal circulation of water or its stagnation often leads to the death of fish. For viviparous breeds, experienced aquarists recommend a flow nursery. They provide comfortable conditions for the life and development of young animals.
It's easy to make a do-it-yourself fish trap. To do this, you do not need to look for specialized tools or materials. Quite enough improvised means. Consider the manufacture of a combined model from improvised materials. To make you will need:
- plastic container (suitable for Korean carrots, seaweed, etc.);
- kapron tights;
- knife (preferably a clerical knife with a thin blade).
The container can be taken in any shape, but it is best to work with a square one. Using a heated knife, cut holes in the container and lid. Please note that it is better to leave a rim of about 1 cm below. This is done so that waste does not fall into the main aquarium and the nursery is easy to clean. Then we pull the stocking over the body. Please note that stockings come in different densities and cell diameters. It is better to give preference to hosiery with small cells. Putting a capron on the body, remove all unnecessary and fix the structure with a cover. For wall fixingaquarium, use suction cups or hooks of the correct length.
A flow jig is a little more difficult to manufacture. It is glued from organic glass. To prevent the fry from getting stuck in the cracks, insulating gaskets are installed. The nursery is connected to the main aquarium using a tube with a curved end. From below, a cover made of nylon with large cells is put on the tube. It will prevent the fry from getting into the main tank and will solve the problem with water circulation. The bottom of the jigger is covered with fine-grained sand.
Rules for keeping young animals
Since the presence of lush vegetation in the nursery is not necessary, care for them is greatly simplified. A compressor is installed in the tank. For these purposes, a sponge filter is suitable, which is connected to the main compressor. A heating element is used to maintain the desired water temperature. The water temperature is selected individually, depending on the phenotype.
Don't forget about lighting. For this, fluorescent lamps are installed that do not change the temperature of the water. The optimal duration of daylight hours is 10-12 hours. Gradually, this time is reduced to 8 hours. The water in the nursery is changed once every 7-10 days. The filters are cleaned twice a week.
A properly designed nursery is a fundamental factor in getting he althy offspring. When designing a jigger yourself, take into account such features as the phenotype, size, quality and number of eggs. This will depend on the size of the sump. remember, thatan incorrectly selected size in 90% of cases leads to the death of young animals.
