How many times a day to feed aquarium fish


The secrets of aquarist: how often to feed the fish

The first, and perhaps the main question asked by novice aquarists - how and what to feed the fish. At the initial stage, this question raises great doubts. You can watch as the fish swim around the feeders gathering food, as much as you like, so beginners can overfeed pets, throwing handfuls of food to them all day. But do not forget that aquarium inhabitants can also overeat, which will have a bad effect on health and water.

At the beginning of the conversation it may seem that this question is easy and unambiguous, in fact, everything is much more complicated. If you want to become a real aquarist, and not the unfortunate host, who once a day throws flakes to their pets, you will have to thoroughly study the issue of feeding the aquarium inhabitants and find their individual approach to them. Proper feeding is a pledge of healthy fish that behave actively and beautifully shimmer with the best flowers.

How many times do you need to feed the fish

Practice shows that most fish lovers choose the right feeding tactics. But, sometimes you have to deal with neglected cases when the owners are addicted and overfeed the fish so that they suffer from excess weight and physically can not swim. At the same time, the excess feed begins to rot, forming a real green swamp with all the ensuing consequences. And this is not surprising. After all, there is no one universal algorithm for feeding all types of fish, so the question is how, what and how much to feed the fish becomes critical.

A beginner aquarist is misled by the fish themselves. They begin to swim at the trough and look lonely into the front glass, as if asking for some more food. However, it should be realized that most fish will continue to beg for food even in moments of overeating, such is their nature. This is especially true for cyclides.

The first and basic rule - limit feeding to 1-2 times per day. This rule applies to adult fish. Fry and teens are fed more frequently. The ideal is a portion that is eaten in the first 3-4 minutes. The norm is observed in the event that no food does not have time to touch the bottom. The exceptions are catfish and fish that feed from the bottom. For them, it is better to use a special feed. Of course, it is impossible to forbid catfish and other herbivores to eat plants and algae, but this is a natural process that will not make them worse. If you are afraid that the fish do not get enough food, then follow their condition for a week.

It is very important to observe the portions and not to overfeed pets. A well-running aquarium has its own microclimate, so excess food can cause imbalance. Remains of feed fall to the bottom and start the process of rotting, which spoils the aqua and causes the formation of harmful algae. In addition, ammonia and nitrates increase in water, which adversely affects all residents.

If you periodically suffer from dirty water, the presence of algae and fish diseases, think about how often you feed the fish and how much food you give them.

The main types of feed

If at intervals it became clear, then with what to give them, not really. Aquarists use four types of feed:

  1. Live food;
  2. Branded;
  3. Vegetable;
  4. Frozen.

Ideal if you will combine all types of feed. In this case, your fish will be healthy and will give you an aesthetic pleasure playing its colors. It is not excluded that fish will eat only vegetable or only protein food, it all depends on the breed of aquarium inhabitants. In nature, someone chooses a vegetarian lifestyle, but someone does not mind to eat their own kind. But if you disassemble most of the fish, it is better to use a mix of several feeds. Purchased branded food can be used as the main food, regularly please fish with live food and sometimes give vegetable food.

If you decide to go under this scheme, then pay great attention to the choice of branded feed. It is better to give preference to well-known brands that have been on the market for more than one year and are tested by experienced aquarists. This food is suitable for almost all fish. It is balanced, it contains the necessary vitamins and trace elements. You can find it in any pet store. Do not confuse branded feed with dry. Food consisting of dried daphnia, cyclops or gammarus is not the best food for the daily diet of your fish. It is not desirable to feed with such food, because it is deficient in nutrients, it is poorly absorbed and, among other things, is an allergen for humans.

Food live food - the most preferred option. The fish should be given regularly as an additional feeding every other day. Like people, aquarium residents love a variety of foods, so try to alternate food as much as possible. The most common are the chimneyweed, bloodworm and coretil. The only, but very significant disadvantage is that this type of food is most often mined in its natural environment, which means that it is possible to bring the infection into your water body. It is best to freeze it before feeding fish. This method kills a number of harmful bacteria.

Featuring an alternative to live food - frozen. Agree, not everyone can be measured with the settlement in the fridge of live worms. For such there is an alternative - frozen worms. They are easy to dose, they are stored for a long time, contain a full set of vitamins. If you carefully study the pet stores, you can find miksovannyh species, where in one pack will be all three popular types of worms.

Vegetable food is an integral part of fish life in the natural environment. Most fish will have to try and cook green food. Of course, feeding predators with grass is stupid, but the rest will gladly enjoy the greenery suitable for them. It is difficult to give general recommendations, since different fish prefer different feeds. There are several options for plant foods:

  • Pills;
  • Flakes;
  • Branded;
  • Natural.

To natural can be attributed cucumber, zucchini or cabbage. Such feeding will allow you to enjoy your clean aquarium with healthy and beautiful fish. With proper feeding, the lifespan of the fish increases.

How often and how much to feed aquarium fish?

Anyone who has at least a little experience in breeding aquarium fish knows perfectly how important the proper feeding of fish is. And this is not always easy - because each breed needs certain feed.

One needs a lot of protein, others need a large amount of carbohydrates. It depends on many factors - the size of the fish, its origin and lifestyle. So, sometimes it is not easy to find exactly the kind of food that will benefit your pets.

Of course, it is worth knowing not only what, but also how much fish should be fed in order not to harm them. And again it depends on the needs of the fish.

Remember: large and mobile fish need a lot of feed.

For example, a small barbus burns so much energy, flying from one corner of the aquarium to another, that it needs to consume much more food than the roosters, the larger fish, who lead a very calm and unhurried life. But in any case, it is enough to give the fish as much food as they can eat in five to seven minutes. Later, they no longer eat with such appetite, and some of the food is at the bottom, where it rots and spoils the water.

To distribute the food between the fish equally, it is desirable to teach the fish to gather at a certain time or by a signal near the feeder. Then it does not happen that some fish will eat two servings, while others will remain hungry.

It should determine in advance how often you will feed the aquarium fish. The best solution for adult fish is two feed feeds per day - in the morning and in the evening. When feeding, do not forget to easily snap your fingernail on the glass near the feeder - the fish will get used to the fact that such a signal portends dinner, and they will immediately float away.

But if you grow young, two feedings per day is not enough. To fry turned into large and beautiful adult fish, it will be better to feed them four to five times a day. Of course, you do not need to give too much food so that it will not be wasted.

What and how many times a day to feed the goldfish

When you put up such wonderful pets like goldfish in your home aquarium, the question immediately arises: "How and what to feed these cute creatures?". In fact, feeding the fish in the aquarium is not difficult. First, it is an omnivorous species of fish, and secondly, when pets get used to the owner, they can be given food with their own hands.

Rules for feeding natural foods

Natural food is a food of natural origin (insect larvae, plankton, benthos, plants and algae, mollusks and crustaceans). All food submitted to the fish should be of small size so that it can be captured by mouth. Fry and juvenile fish should more often eat live and dry food to be able to grow beautiful and healthy. Before spawning, males and females are also given live food with protein, which serves as an additional stimulation to spawn.

Take a look at feeding goldfish with worms.

Adult goldfish love vegetable food more. Consider that it is better to feed young animals with daphnia, bloodworm, pipe worker, coretre, pieces of squid, dry sami. By the way, adult fish should also receive this food, but in smaller quantities. Food for adults is easy to cook with your own hands and at home. Take a kitchen grater, and rub cucumbers, zucchini, carrots, and pumpkin on a shallow surface. You can freeze it in the freezer, and defrost it later (only once!), And give it to pets.

Pet stores sell dried food with fiber, which is intended only for goldfish. This feed is very useful for digestion. They can also be fed with aquatic plants - duckweed, wolfia, and robeberry. They can be grown at home specifically as a feed for your pet. Or, plant these plants in an aquarium with goldfish, and if there is a shortage of food, they will feed on their juicy leaves. Ryaska need to feed the fish only once a day, so make sure that there is no overfeeding.

If you are going on vacation, and no one to leave the fish - then plants with soft leaves (including Lemna) will be an excellent food for starving pets. Gold fish will be enough for one week, they are unlikely to lose weight, but do not overdo it with a vacation. Consider the moment that they remember the owner, and the long absence of a person can also cause stress.

Now about the products from our fridge that are suitable for feeding. Cereals such as semolina, buckwheat, peas, millet are not alien to these fish. They must be salt free and boiled in water. All kinds of goldfish adore peas - peel them off, boil them, chop them in a blender and serve in small portions. It has a positive effect on the gastrointestinal tract. These types of dressings can be served if the home has run out of fish food, or for a more varied diet. Semolina must be washed, non-sticky texture, otherwise the fish will not be able to eat it.

As well as food for this fish fit spinach leaves, nettle, lettuce, dandelion, dill or parsley. Surprisingly, this pet is practically everything that people are used to, which is why it is so popular with novice aquarists! Do not forget that these fish - avid eaters are prone to overeating. Feed them 2 times a day, in small portions that they can master in 5 minutes. Give animal and live food once a day, and the rest of the time - vegetable food.

You can alternate types of feed, and make a menu: give several times a week live food (30% of the diet), and 70% - vegetable. After the meal, the fish leave behind a lot of waste in the form of feces. This means that the aquarium should be cleaned on time: the bottom siphon and water filtration. Once a week, update 25% of the water for fresh and clean, so that food remains do not decompose, polluting everything around.

See how goldfish eat a leaf of lettuce.

Branded fish food

In addition to natural food, goldfish can be fed and branded feed. Manufacturers offer a variety of supplements containing vitamins, minerals, fiber, larvae and other nutrients. Branded food helps to give the fish a brighter color scales, they are harmless in acceptable quantities. It is better to feed branded food 1-2 times a week, although some species are possible more often. All of them are presented in the form of chips, granules, sticks.

How, what and how much to feed Goldfish?



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 hard boiled cereals: 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!

I feed my goldfish with the following formula:

Resurrection - live food, Monday - Wednesday is dry and substitutes, Thursday - duckweed, Friday - Saturday - dry and duckweed.

On such a feed my scrofulous - fat and fluffy !!! :)

How many times a day to feed aquarium fish?


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.

How many times a day do you need to feed aquarium fish?


Feed the fish need 1-2 times a day, giving as much feed as they eat in 5-10 minutes. Nocturnal fishes can be fed 1 time before turning off the lights or under the light of a blue lamp. Malkov need to feed more often. Normal portion of feed for an adult fish is 2-5% of body weight, for fry - 15%. It is advisable to develop a feeding schedule: feed the fish at the same time. Do not be afraid that your pets will starve. Even if you give them less food than you need, it is much better to overfeed. First, in warm aquarium water, the remnants of food deteriorate quickly, the fish will not eat it already, and you will have to clean the aquarium more often, as decaying food pollutes the water. Secondly, not only people, but also aquarium fish suffer from obesity. While a person may voluntarily go on a diet or reduce the usual diet, the fish do not have this consciousness. Some species of fish are prone to gluttony. They will eat everything you offer them. As a result - obesity, which can lead to infertility and death of fish.

Yury Balashov

fry 4-6 times.
young fish - 3-4 times.
adults 1-2 times, once a week - hunger strike.
in the case of * riding, you can not feed for 2-3-4 weeks, a small part of the fish will die from hunger, but the rest will survive, just lose weight. If you leave the whole household to your friends and neighbors, then all the fish will simply die from the abundant food and non-serving aquarium.
Good for you fish, good luck.

How many times a day to feed aquarium fish

Svetlana Kosareva

They are fed once a day, the amount of food they eat in five minutes. For catfish do not worry this night fish he eats at night with what remains at the bottom between the pebbles. I assure you that if he lacked, he would immediately wake up and eat together with everyone.


Usually he writes on feed like this: it is advisable to feed a couple of times a day so that the fish eat ALL food somewhere in 3-4 minutes, throw it so that it DOES NOT FALL ON THE GROUND if there is no one to eat it up later. For example, eating my neons did not catch food - they rarely lift from the bottom. And of course, it’s better to always feed them in such a way that they would rather underfeed rather than overfeed, since I don’t know of a single person whose fish would die of starvation. And if there is no food left in the aquarium, the water will deteriorate.


I also have an aquarium of 40 liters. I feed twice a day - in the morning and in the evening. I pour a small handful, for two fish eats everything for a minute. If the food stays at the bottom - siphon, about once a week. For catfish there are special bottom feed. It is heavier and other fish do not touch them. At least I have it.

Zoya Usmanova-Malashkov.

Catfish love moth. I feed my moths 2 times a day. I have a simple catfish, a labo, a frog, 4 patchillians, 4 swordsmen, 3 mollies and honey gourami. And all this in 20 liters. aquarium.

Kuchumova Alisa

I feed mine 1-2 times a day in the morning with dry tetra flakes, in the evening with a live moth of small ice cream. I just have 2 eels that eat only live food. I don’t skip nursing feeding, and in the evening I can feed even once. You can arrange fasting days - 1 time per week.

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!
