How and what to feed tropical fish

Living in the wild tropical fish are not spoiled by an abundance of food, and therefore can long without it. But during the rainy season, forage is enough, this time the fish reach maturity and spawn. In favorable conditions the young grow up without any problems and becomes sexually Mature. The main task of the aquarist is to find a substitute for natural forage, To determine the correct composition of the diet have to be able to distinguish three fish groups.

a) fish feeding on plant food (herbivores)

b) fish feeding on small aquatic fauna, zooplankton and bentoel and plant food (omnivorous)

b) the fish, feeding at an early age small, and later a major animal food and fish (carnivores).

In the natural environment with an abundance of food a certain kind of fish chooses the one that fits him best, and in captivity, fish are totally dependent on what they will offer. So among aquarists can often hear that this or that kind of got used to the unusual stern. However, this can be hidden tricky, because the fish can take the feed of hunger and the addiction to food can lead to later health problems. Good food and regular feeding is especially important for young and breeding fish (manufacturers). Giving the fish a natural food, we thereby satisfy their needs in proteins, carbohydrates, fats, vitamins, mineral homestake. Different is the case with artificial food, which is slowly but surely becoming the predominant element in the diet of aquarium fish. It would have been useful information manufacturer about the components of the feed mixture.

The most important element of nutrition are proteins, which cannot be replaced by any other nutrient. They cause all life functions, especially growth and reproduction. Source of proteins are planktonic organisms, beef, liver, heart, and egg yolk. Carbohydrates are the main source of energy. Since the body is able to produce them from the products of breakdown of proteins and fats, their presence in the feed composition does not necessarily. Fats are a reserve energy, they are important for the assimilation of vitamins A, D and E. the Body produces fat from carbohydrates and proteins, therefore we can do without them. Mineral substances are important from the point of view of formation of the skeleton, blood, muscles, predatory fish — gastric hydrochloric acid (chlorine), they are important for the development of the sexual organs, etc. are calcium, phosphorus, sodium, potassium, magnesium, sulfur, iron, copper, cobalt, iodine and manganese. Vitamins — biologically very effective substances which in very small amounts absorbed by the body, contributing to its normal development. Lack of vitamins in food is manifested in the emergence of various diseases called beriberi.

Fish nutrition cannot be underestimated, doing monotonous, often nutrient-poor, food. Let us now compare major sources of natural power in nature and in aquariums.

Plant foods in nature, fish are found in the form of algae, soft aquatic plants, seeds, and fruits, as well as in the form of digested single-celled algae contained in the digestive tract of zooplankton, such plant food in captivity is replaced by spinatum mashed potatoes, scalded with boiling water the leaves of iceberg lettuce, kohlrabi, Savoy cabbage tion, coolbaby and nettle.

A useful and important element of food of fishes is worms. In aquariums is mainly rotifers (Rotatoria), sludge (Tubifici-dae), enhitreusom, or angarey (Enchytraeidae) and earthworms (Lumbici-dae). In nature, the diverse fauna of the seabed (benthos).

Shellfish are for a number of species suitable food, and for some species even staple diet. The calcium contained in the leaves are the sinks that are important for skeletal development.

Crustaceans living in nature in all climatic zones, in freshwater and in brackish and salty waters are the most common type of food in captivity. Aquarium fish are often fed with Daphnia (Cladocera), Cyclops (Copepoda) and nauplii stages of Anostraca, known among aquarists as Artemia (Artemia salina).

Rich forage reserve in the tropics are the larvae and imago (adult stage) of insects. Accordingly, aquarium fish feed on the larvae of mosquitoes (Culicidae and Chironomidae — Chironomus larvae) and adult fruit flies (Drosophila), which are specially bred for feeding purposes. Good food for large predatory fish and are predatory nymphs of dragonflies (Odonata) larvae and some water beetles. Food many species of fish are small fish that often play an important role by participating in the processes that encourage to spawn (genus Astronotus, Serrasalmus, etc.).

Another source are dried and lithophile feed from natural raw materials or sliced, chopped or scraped beef heart and meat. A mixture of liver and spleen binds agar. Meat of marine fish, caviar and shrimp meat are a good substitute for natural forage. However, the composition analysis of beef showed that it contains an enzyme, demoralizing vitamin b and causing its deficiency in the body of the fish. So in that case, if the fish have a long time to feed beef heart, powdered mixture is recommended to apply the drug vitamin b-complex or regularly to feed the fish spinatum puree.
