Cladocera inhabit different fresh water, including puddles, ditches, moist ravines, and so multiply very quickly, every 3-4 days produce new offspring. Copepods are also widely found in freshwater. About 250 species, especially the popular Cyclops (both have the same frontal eye). The value of the Cyclops in the range 1,5 – 5 mm larvae, respectively, are also of different lengths. Therefore, by sorting can pick up food for fish of different ages and sizes. All shellfish is well tolerated temperature fluctuations, and catch them all year round. The prepared food must be stored in a low wide vessel, placed in cool and low light place. For better preservation of water in which food is stored are periodically purged.
Dead shrimp should be removed for washing. Variety of tables and insect larvae living in water. Y aquarists are especially popular mosquito larvae – zvontsev, more commonly known as crank. They are developed in weakly running or stagnant water bodies and wet muddy ground. Mined moth in the same way that Tubifex stored in a damp cloth, wrapped in several layers of dense, dry paper. The package is placed in a cool place. With a large amount of food it needs to be periodically (1-2 times per week) to wash.
The larvae of other mosquitoes – koretru – caught in the water column usual net. Koretry advantage in that it is not buried in the substrate material disadvantage – low energy value compared with the bloodworm. In addition, the larva – a predator may attack on individual fry. Koretru possible long-term storage in low voluminous vessels at low temperatures. Do not hesitate to take mosquito larvae floating in shallow puddles on the surface, eggs and tadpoles and frogs frogs, Drosophila. Last bred at the bank with the remnants of slightly sweetened fresh fruit or compote. The best in quality, of course, is a live feed, but Pratica often use substitutes. They are dry and combination. The first is most often composed of dried crustaceans (Daphnia, Cyclops). Methods of preparation is simple: caught shrimp are placed on the gauze frame in a well ventilated, sheltered from direct sunlight, and dried up condition. Store stocks have in closed vessels. But one of the recipes for mixed feed. Take meat, beef liver, cheese, caviar, frozen fish, algae, nettle leaves, and flour in small quantities and in roughly equal proportions, double-grind in a meat grinder. The resulting granules are dried (available on the radiator steam boiler) and stored in a hermetically sealed container, in cool place. In recent practice of freezing live feed in freezers refrigerators (without water), displaying them on a board with a thin layer. Many fish need to be systematically feeding. In this capacity, useful plants (lettuce, spinach, dandelion, nettle, etc.) and animal proteins (eggs frozen fish, meat) and egg whites, cottage cheese, bread.
