Frozen food for aquarium fish: types and rules of feeding
The nutrition of aquarium fish should be complete and varied. This is the key to strong immunity, good growth and effective reproduction of aquatic life. Therefore, fresh frozen food has gained particular popularity among aquarists. With this food, the fish get the necessary proteins, fats and carbohydrates.
Peculiarities
Initially, there were exclusively live food, then in addition to them came dry and frozen, while the latter of which have held the palm among aquarists for more than half a century. Such feeds are easier to store, while they are guaranteed safer from infection by a variety of helminths and bacteria. Their huge consumer appeal is due to their natural origin, which retains all the nutritional value and essential amino acids. In addition, frozen food for aquarium fish is enriched with essential vitamins and minerals that are so important for the aquatic life.
The idea of keeping domestic fish belongs to the Chinese. The first was the crucian carp, which was specially selected with birth defects and malformations (bulging eyes, forked tails, missing fins). This is a familiar goldfish to all of us. In the Russian Empire, the first decorative fish appeared in the 15th century. Europe first saw them only in the 17th century. For Europeans, such an unusual pet was very expensive. They died in large numbers due to the fact that there was an opinion that such unusual creatures feed only on "ether" and do not need any other food at all.
Only over time did people become convinced that aquarium fish still need a variety of organic foods.
What is related?
The main task of the aquarist is to create living conditions as close as possible to the natural environment. At the same time, correctly selected blast-frozen food allows you to get as close as possible to the natural food base. The main advantage of such food: is as follows:
- natural appearance;
- the composition is easy to digest;
- optimal ratio of vitamins, minerals, natural dyes.
They are produced in the form of rectangular briquettes or cubes resembling a chocolate bar. This form is more practical to use. It is stored for three months. A large number of fish eat with great pleasure such foods as:
- bloodworm;
- core;
- tubifex;
- Cyclops;
- daphnia;
- brine shrimp;
- hamarus;
- wolfia;
- shellfish;
- larvae;
- worms;
- shrimp, squid, fish meat;
- with spinach or spirulina.
In pet stores, you can find feed of the same type or mixed, collected according to the principle of species feeding. And also food is provided by age (for large fish or fry). Before buying this or that frozen food for aquarium fish, carefully read the composition and expiration date.
Correct defrosting
Proper defrosting of feed is the key to the successful preservation of all nutrients. Break off a small piece from the briquette, place in a small container, rinsing with running water until completely thawed. It is impossible to give food that is not completely thawed, as ice crystals can damage the stomach and intestines of fish. Feed should be in small portions using a measuring spoon or tweezers. It is important not to throw frozen food into the aquarium. Excess uneaten and melt water will lead to cloudiness and disease in fish.
Important! Defrost as much food as the fish can eat at one time. Re-freezing has a significant impact on quality, significantly reducing its nutritional value.
You can cook frozen food yourself. For this, any live food should be used, except for the tubifex. It is likely to contain harmful substances. The procedure is straightforward. It is necessary to rinse everything thoroughly, place in ice containers, fill with a small amount of water, close the lid and place in the freezer.
However, do not get carried away with this method. Manufacturers use shock freezing, which can not damage the delicate flesh of organisms. The damaged ones lose most of their nutrients and trace elements.
We define quality
Purchase frozen food in the form of a chocolate bar. This shape has the following advantages for small aquariums:
- convenient to use - break off as many briquettes as needed for one feeding;
- this form does not tolerate constant defrosting and freezing; if the appearance is correct, not deformed, then the feed was not thawed during transportation and storage.
The packaging only protects against moisture penetration. When oxygen enters, the contents undergo an oxidation process. Toxic substances begin to form in frozen food, which have a negative effect on the health of the fish. And also visually assess the quality of the feed. Each larva, each piece should be clearly visible. Refuse to buy if everything is hard to distinguish.
The best option is vacuum packaging. The container consists of 5 layers of barrier film, complementing each other. As a result, the product does not oxidize and does not undergo the development of pathogenic microorganisms and putrefactive fungi. And also the shelf life of such feeds is twice as long as that of other frozen representatives.
