How to feed aquarium fish

In order to understand how many times a day it is necessary to feed aquarium fish, it is necessary to understand the peculiarities of their nutrition in their natural habitat. All types of fish borrowed from their natural ancestors taste preferences and diet. What do all the fish usually eat?

Fish nutrition

  1. Herbivores - these fish have a long digestive system, which indicates the habit of often eating small portions. In their natural habitat, they eat algae, plants, fruits, and seeds.
  2. Carnivores - have a large stomach, so they eat a lot, but not as often as herbivores. In nature, these fish eat dead animals, small fish, insects, invertebrates, birds, amphibians.
  3. Omnivorous - the diet of these fish several times a day, they prefer both vegetable and protein foods.

See how to make vegetable food for aquarium fish.

According to the diet and diet, their aquarium fish need to be given such food that suits them. Typically, domestic fish fed live, frozen, dry, vegetable food, which is sold in stores. It is important that food be varied and rich in healthy vitamins and minerals.

Live food should be given to carnivorous and omnivorous fish. It is a bloodworm, a pipe worker, a daphnia, a coretera, an infusorium, rotifers, and gammarus. They must be stored in the freezer, they quickly deteriorate. Fish fry need to be grown on live food, due to protein, they become resistant to diseases. Also, as a live feed, small fishes are served with veal, minced fish, chicken meat, liver, invertebrate meat, chicken eggs. Vegetable food is necessary for herbivorous and omnivorous fish - these can be vegetables, fruits, algae, plants, cereal porridge.

Once a week, the fish are satisfied with a fasting day, or a mini-hunger strike. It cleans the intestines, eliminates the effects of overeating, helps to heal sick fish. In the natural environment, fish can live without food for a long time, so a one-day hunger strike will not harm them.

About the regime of feeding in captivity

To feed the fish you need so that they do not overeat, and were full of food. Diet depends on the age of the pet and the characteristics of its digestive system. Adults usually eat 2 times a day, which is enough for them. Youngsters aged 1-2 months should eat 4 times a day. And fry up to one month old need to be fed every 3-6 hours. During the spawning period, the fish should be given less food, sometimes not feeding the first few days after breeding. Two weeks before spawning, producers, on the contrary, should correctly produce more live food.


No matter how many fish you keep, you need to give them all the food at the same time. Begin in the morning, an hour after turning on the lights. The last feeding should occur 2 hours before the lighting is turned off. The question of novice aquarists is how much food to give, and how often? Give us enough food so that they can eat it in 5 minutes. Do not feed often, but in small portions, so that they completely swallow them. Unfinished leftovers can be removed with a net to avoid rotting.

Feed pellets depend on the age and size of the fish. Juveniles should eat food that does not exceed the size of their eyes. Dry food in the form of granules, flakes and tablets is recommended to be ground to dust. Adult fish like to grab larger particles of food, they do not eat dust. In order for all the inhabitants of the household water body to be satisfied with feeding, install special feeders for dry and live food in the tank. Of these, food is not frayed, and pets can eat it calmly.

See how to properly feed dry fish aquarium fish.

How to feed the fish

There are general feeding rules for all fish that need to be followed constantly:

  • Properly feed the fish with the food that is right for them, consider the physiological characteristics of all species living in the general aquarium.
  • Do not overfeed your pets - give food not too often, in small portions.
  • For aquarium fish, the best nutrition is a variety of foods.
  • No matter how much food you put in the tank, remove the remnants of it after the meal.
  • The number of meals should correspond to the size and age of the fish.
  • Do not feed the fish immediately after turning on the light, or before bedtime.
  • In the diet of aquarium fish should be natural food, and not just artificial, purchased.

What should get the fish from the feed received

How many times a week should a fish eat, and what portion of nutrients does it need to receive from food? It all depends on individual calculations. Carnivorous and omnivorous fish can be fed according to this scheme:

  • The first day of the week - dry food of the first type (chips or pellets) once a day.
  • The second - dry food of the second type, 1 time per day.
  • The third - live food (for example, artemia or bloodworms), 1 time per day.
  • The fourth - dry food of the first type, 2 times a day.
  • Fifth - dry or vegetable food, 2 times a day.
  • The sixth is live food (the pipe-worker, daphnia) and vegetable food.
  • The seventh - unloading diet.


Feeding in an aquarium can be made differently, and you can make your own scheme. Be sure to alternate between dry, live and vegetable food. If the fish is herbivorous, it should eat only vegetable and dry food (spirulina tablets). Do not forget about the vitamins that should receive a pet for a full life. If you buy food of famous brands, look at the composition, it indicates all the trace elements and vitamins that the fish will receive after eating.

  1. Vitamin A is needed for cell division, in particular in fry and young. Lack of this component can cause growth retardation, curvature of the spine and deformation of the fins, and constant stress.
  2. Vitamin E - plays an important role in the development of the reproductive system.
  3. Vitamin D3 is essential for the development and growth of the skeletal system.
  4. Vitamins of group B (thiamine - B1, riboflavin - B2, cyanocobalamin - B12) are necessary for the normalization of metabolic processes in the body.
  5. Vitamin C (ascorbic acid) is involved in the formation of bone system and teeth, strengthens the immune system, improves metabolism.
  6. Vitamin H (biotin) - is required for proper cell formation.
  7. Vitamin K is a fat-soluble vitamin, it is required for the synthesis of proteins, provides blood clotting.
  8. Vitamin M (B9, folic acid) - develops the immune system, the circulatory system. Improves scales color.
  9. Vitamin B4 (choline) - required for fish growth, synthesizes the amount of sugar in the blood.

How many times to feed the fish in the aquarium?

Fish, like cats, dogs and other pets, need a varied and sufficient diet. When planting water inhabitants, it would not be superfluous to ask how many times you need to feed the fish in the aquarium, at what time it is best to do it and in what portions to fill the food.

How many times a day to feed the fish?

Feeding can be one-time, but it is more preferable to feed them twice. At the same time, morning feeding should be carried out at least 15 minutes after switching on the lighting, and the evening one - 2-3 hours before bedtime. For night dwellers (catfish, agamix, etc.) feeding is carried out at dusk, when the light is extinguished, and the rest of the inhabitants of the aquarium sleep.

The duration of each feeding should not exceed 3-5 minutes. This is more than enough for the fish to eat, but not to eat, and the food does not sink to the bottom. In general, the rule works with fish - underfeeding is better than overfeeding.

The daily feed rate is calculated approximately as 5% by weight of the fish. If, after saturation, the feed continues to float and settle to the bottom of the aquarium, it should be caught with a net to prevent its rotting.

Once a week for fish you can arrange a hungry day. Obesity of fish leads to their death much more often than malnutrition. Because you never need to give the fish feed above the norm. In addition, hunger has a positive effect on sexual activity and on the restorative ability of fish.

How many times a week to feed the fish in the aquarium?

As already mentioned, food for fish should be varied. Therefore, it will not be superfluous to know how many times to feed aquarium fish with live food. An approximate weekly diet of aquarium fish may look like this:

  • Monday - dry food;
  • Tuesday - dry food;
  • Wednesday - live food, bloodworm, artemia;
  • Thursday - dry food;
  • Friday - dry food;
  • Saturday - live food + duckweed;
  • Sunday is a hungry day.

How much and how often to feed guppies?

It is guppies that open for most aquarists an amazing and wonderful world of aquarism. Indeed, most often these fish are turned on by novice aquarists in order to gain nursing and breeding skills.

And this is a great solution. On the one hand, guppies are among the most unpretentious fish. They are ready to eat any food and are able to live in the smallest aquarium - even in the usual three-liter jar. But at the same time they are surprisingly diverse and beautiful. Huge tails of different shapes, bright colors - thanks to all this, a flock of guppies looks great in good light. Of course, if you only recently brought them, then you probably wonder how much to feed the guppies and what.

In general, there is nothing complicated. To feed the guppy you need so much food, which will be eaten within five minutes. More feed is not needed - later the fish eat without much appetite, in reserve. Therefore, part of the food falls to the bottom, where it decomposes and spoils the water. And, of course, the extra food eaten turns into fat deposits, which will negatively affect the health of the fish.

So it will be useful to remember one of the main commandments of aquarists - it is better to underfeed than overfeed.

Guppy food quality is also not very picky. In general, you can even grow several generations of guppies, using only dry food - daphnia and gammarusa. But then you should not hope that the fish will be really big and bright.

So, if you have such an opportunity, it is better to combine dry fodder with bloodworms and pipemaker.

It is equally important to know how often to feed the guppies. The best solution would be two meals. Enough to feed the fish twice a day - in the morning and in the evening.

But this applies only to adults. If you grow fry, it is better to feed them three times a day. Live dust or a hard boiled yolk of a boiled egg, pounded and dissolved in water, is perfect for feeding.

But you have to be careful with him - the water may start to deteriorate from him.

How to feed aquarium fish?

Proper and rational nutrition of fish - a guarantee of health and longevity, not only adults, but also future offspring. Let's talk a little about nutrition, volume and feeding regimes. What feed is better to use, whether it is possible to give pets homemade or still better purchased.

It's no secret that nutrition is one of the most important components of life. From its quality, quantity and composition depends on how long and happy will be the life of an organism. Such arguments are valid for aquarium fish too. If you do not want your small water-loving pets to be stunted and constantly sick, you need to feed them with the right food that suits them. Also, do not forget about the balance of proteins, micro and macronutrients, fats and carbohydrates.

Food in vivo

In order to understand how to feed aquarium fish, you need to know what they eat in their natural habitat. As a rule, for different types of fish it is quite dissimilar products.

So what do fish eat? Consider this question in more detail.

Herbivores have a long digestive tract, which indicates the need for frequent feeding in small portions. The feeding of such fish in the natural environment, as a rule, consists of a variety of algae, plant particles, fruits and seeds.

Carnivorous species have, in turn, a pronounced large stomach, which means they must eat food in large quantities a small number of times. Under natural conditions, they usually feed on live or dead small animals, insects, birds, invertebrates, amphibians.

Omnivores. Even on the basis of their name, it becomes clear that such species prefer any acceptable food.

Which feed is better?

Each species requires a different food, so it is impossible to formulate a diet for all aquarium inhabitants at once. Only a specialist can help you with this. Of course, you can use homemade food in the diet of waterfowl, but you can not always take into account the full range of essential macro-and micronutrients. And the preparation of the feed itself requires a lot of time and taking into account all the technological nuances.

As a rule, fish kept in aquariums are fed mainly with dry food and insects, protozoa, sold in pet shops. It is advisable to add to this a small percentage of allowed for this type of natural products, such as fruits.

Live food is necessary for carnivorous and omnivorous fish, especially during the spawning period. To it can be attributed, for example, moth, pipemaker, daphnia, ciliates. Store such food in the freezer refrigerator. But the main thing is not to keep it for too long. There is a time for everything.

Fry raised on animal feed are more active in behavior and most resistant to diseases. The younger generation can be fed with yogurt. It contains the necessary bacteria and vitamins.

As a living food, you can use minced fish, poultry, liver, invertebrates, eggs. And from plant foods algae, vegetables, fruits, cereals are perfect.


Hunger for body benefits

Approximately 1 time a week, the fish need to organize a preventive hunger strike. This will help cleanse their intestines. Especially it is not necessary to burden the food of sick individuals, it will slow down the healing process. It is better to hold them for 2 days without food, do not worry, they will not die of hunger. In natural habitat, they are not able to eat for very long.

Feeding mode

Feeding regime, as a rule, directly depends on the age of the fish. Adults have enough 2 meals a day. This completely covers their needs. At the same time, the fry from 1 to 2 months are fed 4 times a day. Up to 1 month - every 3-4 hours, young fry - every 6 hours.

During spawning, fish-producers are cut back on food, not feeding the first couple of days, and after giving significantly less food than during normal times.

Feeding time should be no more than 5 minutes. This gap is enough to fish ate. After that, it is necessary to remove the remains, otherwise they will begin to rot and spoil the entire internal environment of the aquarium.

It is very important to remember that the size of food particles for different age groups is also different.

For very young fish, it should not exceed the size of the eye, otherwise the fry simply will not be able to eat it and will always remain hungry. Therefore, large dry food need to fray fingers in fine dust. You can buy ready-ground powdered fry food.

At the same time, adults are not enthusiastic about eating crumbs at all, so they need more impressive pieces.

To ensure that all residents of the aquarium will be satisfied, you can resort to using special feeders (for live and dry food). Such troughs are attached to the aquarium and they are already feeding there directly. So the food does not spread across the entire surface of the aquarium, and the fish can safely eat it.

Feeding rules

Much has already been said about feeding rules. However, it is necessary to combine them into one section for the convenience of readers.

Basic feeding rules:

  • feed the appropriate food for this type of fish;
  • do not overfeed;
  • give a variety of products;
  • clean up the rest of the feed net;
  • the number of feedings should be commensurate with age;
  • do not feed at bedtime;
  • The presence of natural food in the diet is required.

When starting any living creature at home, it is important to always remember that it is not only joy, but also a great responsibility. Without proper care, any living thing will not live long. Not an exception and fish. Therefore, watching your diet, do not forget about little friends. And then they will delight you with their beauty and playful mood for a very long time.

How, what and how much to feed Goldfish?


FEEDING GOLDEN FISHES

AS? WHAT AND HOW MUCH?

Goldfish - extremely playful, cheerful and voracious creatures. They quickly get used to the person of their breadwinner, and as they approach the aquarium, they jump out of the water like piranhas with hungry eyes. This behavior of your waterfowl pets can be repeated 10 times a day, but this does not mean that the goldfish are hungry all this time. This is just a conditioned reflex. It is necessary to feed your pets 1-2 times a day with one pinch of dry food. This is quite enough for their normal growth and development. If you feed more often, the fish will behave very sluggish, in addition their life expectancy will be reduced.

Despite the fact that the process of feeding goldfish can bring you a lot of pleasure - do not abuse it. In fish, there is no sense of saturation. Do not forget about it. So do not overdo it. And your pets will long please your eyes and soothe raging thoughts.
And now from the lyrics, to the point!

Goldfish need a balanced diet.Their diet should include both live food - bloodworm, artemia, daphnia, rotifers and other food: dry and especially vegetable.

If we talk about proportions, then in my opinion for goldfish, this proportion looks like 40% live, dry and 60% vegetable food.

Live food, adore all the fish and gold is no exception. When keeping Zolotuh in an aquarium, it is better to use frozen live food, as they are safer than full-scale.

Dry feed - a universal remedy for feeding any fish. Manufacturers of aquarium feed took care of the usefulness of the diet. Therefore, if you wake up to feed goldfish only with such food, then this will be quite enough for their well-being. But if you want to feed your goldfish to be elite))). It is necessary to introduce vegetable feed and only natural.

How is this achieved ?! Yes, very simple. You need to breed Leopard or RicciaWell, it is very golden love this aquarium vegetation.

Here, please see how much duckweed grows in my week in an aquarium with scalars. All she goes to feed goldfish.
Economical and non-GMO!

As it is known, duckweed and riccia grow very quickly and do not require special conditions for maintenance. For a week you will grow it on a scale sufficient for goldfish to feed. It should be diluted in a separate aquarium and transferred to scrofula 2-a - 3 times a week. That's all you need.

It is necessary to distinguish the feeding of goldfish in the aquarium and in the pond.

For feeding goldfish in a pond, it is recommended to use meat chips mixed with bread, as well as cooked porridges: buckwheat, oatmeal, millet, etc. The pond must be with vegetation !!!

If anyone is interested in this question, I recommend you to talk with our user "Muri", she is a noble ruler of goldfish in the pond!

How to feed aquarium fish?

Elena Gabrielyan

Adult fish are fed once a day, 6 days a week and given just enough so that within 2 to a maximum of 5 minutes they are completely eaten without any residue, 1 day should be unloading (fish are not fed). It is best to feed in the morning an hour after turning on the light in the aquarium.
Teenagers are fed 2 times in the morning and evening in the same morning one hour after the light is turned on and in the evening one hour before it is turned off.
Water NEVER CHANGES completely, but only replaces 1 to 7 to 10 days with a ground siphon of 10-20% of the total.

Olga Valanina

It depends on what kind of fish you better go to the zoo shop to get tips. Then they will tell you only how to feed crucians.
It is necessary to change the water correctly, if you drain more than you need, the fish will die. How to do it all and a hose for changing the water is in the zoo shop.

Natalia A.

It all depends on what kind of fish, adult fish are fed 1-2 times a day, once a week, unloading, teenagers 3-4, men more often and little by little, during the feeding time Lena stated everything, I will repeat a maximum of 5 minutes the feed should to be eaten, it is better to underfed the fish than to overfeed, a half-starved fish is a healthy fish, it does not change correctly, but water is replaced, all the dirt from the bottom is collected with a siphon, while part of the water is drained, freshly replenished is replenished, substitutions are made every 7-10 25-30% days.

Sergey Romanov

Regardless of the size and type of fish, you need to feed once a day (adults) the feeder should be in the same place, food should be eaten within 5-10 minutes, it is desirable to remove the remains. The best food is a small bloodworm, do not forget to wash it so that the infection in the aquarium is not brought, if the feed is dry, then select, depending on the type of fish, bottom feed sinking granules that live near the surface (like iris) with floating granules. Water can be changed 2-3 times a month, with equal intervals of 1/5 of the volume, in this case, you can not even defend the water. And there is a lot of literature on this topic, read do not be lazy!

How many times a day to feed aquarium fish?

SEREGA_

1 time. But the feeding time depends on the type of fish that you keep in the aquarium. Somiki are activated closer to the night. Labyrinth day or morning.
I feed mine closer to the night. 1 - all that falls is eaten by fish living in the middle layers, on top of Gourami, Lyalius ... Well, then heavy artillery turns on - catfish)))) Thus, everything that has fallen to the bottom is eaten and no food remains. for the whole day they manage to pick up what they have not finished.

Feeding fish in the aquarium
Inexperienced aquarists often make the mistake of overfeeding their fish. Usually it has the most unpleasant consequences. Overfeeding does not always cause direct harm to the fish, but it can lead to serious water quality problems that can cause stress or even death to the inhabitants of the aquarium. The harmful effects of overfeeding mainly boil down to two aspects:
• The uneaten food decomposes quickly, leading to the formation of ammonia.
• Excess food (especially protein) absorbed by fish leads to an increased release of ammonia by the fish. An increase in the ammonia content resulting from these processes may cause a depletion of the biological filter media, and this leads to the accumulation in the water of an ammonia tank, which is toxic to fish. In the case of regular overfeeding, the biological filter can adapt to this and cope with elevated ammonia levels. However, the end result will be increased organic pollution, which can lead to mass development of parasites, such as planarian and cochlea, as well as increased formation of nitrates. In the latter case, a more frequent change of water will be necessary to prevent the poisoning of fish with nitrates and such a phenomenon associated with an excess of nitrates as the "blooming" of water (rapid development of algae).
It can be concluded that fish require much less food than other animals of the same size. This is partly due to the fact that fish are cold-blooded (poikilothermic) animals and therefore they do not need to convert food into heat. Many fish are capable of neutral buoyancy, so they do not need energy to overcome the force of gravity. Thus, if you compare fish with other animals of the same weight with them, then the fish need less energy.
When the aquarist gets enough experience, he will learn to count the strictly necessary amount of food. But for beginners, there is one important rule: at one time, fish should be given as much food as they can eat in about five minutes. If the fish are overfed or a large amount of their food has accidentally entered the aquarium (for example, a can of food has fallen), the excess must be removed from the aquarium as soon as possible before it begins to decompose. As mentioned earlier, the possible types of feed and the frequency of feeding depend on the type of fish, and in addition, they can be influenced by environmental factors. Most fish species, as well as fry of almost all species in nature, feed continuously, so it is better to feed them in small portions several times a day than to give a large portion once a day. When keeping a common aquarium with many different fish, it is usually recommended to feed them two or three times a day in small portions. Exceptions are fish that feed on large prey. For example, some predators can eat a whole fish, which is only half the size of itself. Such fish need to be fed only two or three times a week, they may even refuse extra food if they are offered it.
The aquarium should be carefully monitored so that all fish constantly receive their share of food. Fish that swim too slowly, as well as timid and nocturnal fish, may well miss feeding time. The same applies to individual fish that are at the lowest level of the aquarium hierarchy. Finally, feeding time is a great opportunity to check if all the inhabitants of the aquarium are in place and in good health. Loss of appetite should always be viewed as a warning signal that something is amiss.
