Shrimp in a home aquarium. Giant freshwater shrimp farming business
Exotic appearance, bright colors And interesting behavior Freshwater shrimp are increasingly becoming residents of aquariums. The most popular among owners of artificial home ponds are small specimens, ranging in size from 2 to 5 cm.
Even a novice aquarist can keep them. Such shrimps, unlike their larger relatives, do not consider themselves predators, and therefore are not at all aggressive and are quite content with food that falls to the bottom.
There are quite a few species of freshwater shrimp, but only a few can be considered suitable for indoor aquariums. For the first acquaintance, small shrimp of the Caridina genera (lat. Caridina) and Neocaridina (lat. Neocaridina). They will not only provide company to peaceful fish, but will also clean their habitat from the remains of dry or live food and excess algae.
By the way, contrary to popular belief, shrimp do not eat algae at all. Such known species small crustaceans, such as Amano (lat. Caridina japonica), which are most often used to clean an aquarium, simply trample the plants with their numerous legs, removing from them the bacterial plaque necessary for their development. Algae cannot tolerate such blasphemous attitude towards themselves, and defiantly stop growing.
Except practical benefit, shrimp have one more advantage - some of them attract with their unusual colors. At the bottom of the aquarium you can find red, blue, yellow, black and even striped crustaceans. These are the so-called cherry shrimp, bumblebee shrimp, tiger shrimp, crystal shrimp, etc.
Truly, they are ideal for small ponds, as they are unpretentious and easily reproduce in captivity. True, they have one drawback - passive behavior when molting. Instead of hiding, the soft shrimp lies flat for several hours, becoming easy prey for curious local residents.
All aquarium species freshwater shrimp appearance They resemble crayfish, but are more mobile and peaceful. They may also have a transparent shell, which emphasizes their fragility and decorativeness. In addition, it should be noted that many shrimp change their color in an attempt to adapt to environment, under stress or sudden changes in temperature.
IN home aquarium a special pump will create the flow, the filter will purify the water, and the aerator will saturate it with oxygen. It is better to put soaked branches and stones at the bottom, and organic matter processed by bacteria will be a suitable soil. Also good neighbors there will be mosses and cover plants for the shrimp.
Small crustaceans feed on live, frozen, vegetable and dry food of any size. It's funny to watch a shrimp trying to eat a bloodworm larger than itself. They get food from all nooks and crannies, preventing it from rotting and spoiling the water, which, combined with their ability to fight algae, makes them wonderful aquarium orderlies.
Aquarium - great option for those who want pets to live in the apartment, without feeling remorse for the fact that there is a catastrophic lack of time to care for pets. What if you add them to familiar fish? aquarium shrimp– the life of a small underwater world will be transformed and enlivened. Shrimp get along well with fish, and they unusual appearance and behavior make watching them a complete pleasure. But in order for the “new settlers” to feel comfortable, it is important to know what conditions are required for their maintenance and how shrimp reproduce in the aquarium.
Comfortable conditions for aquarium shrimp
Breeding shrimp in an aquarium is not difficult. These little crustaceans cannot be called picky: they are practically omnivores - they happily feast on special food and fish food, and will not refuse boiled vegetables.
Shrimp have gained fame as aquarium nurses: they “remove” dead fish and dead plants, thereby regulating the cleanliness and growth of aquarium flora .
You can make excellent aquarium shrimp houses yourself by simply joining together a few scraps of tubing.
You need to feed crustaceans no more often than once every 2-3 days, otherwise they begin to be “lazy”, ignoring their function as filter feeders. And decomposing, uneaten food takes away oxygen from the inhabitants of the aquarium.
To create shrimp good conditions For life and reproduction, several requirements must be met:
- should always be in the aquarium clean water, the temperature of which does not go beyond 15 0 C - 30 0 C (in more cold water reproductive functions stop, and in hotter temperatures the shrimp die);
- you need to create a slight movement of water: standing shrimp will be uncomfortable;
- it is important that the pH of the water is slightly acidic or neutral;
- copper content in water is unacceptable;
- Artificial aeration is welcome, and a low-noise compressor should be selected;
- To prevent crustaceans from crawling out of the aquarium, where they will quickly die, it is worth covering it with a lid.
The decor and presence of plants are also very important - this serves as a shelter for the shrimp during the molting period, when the crustaceans are very vulnerable. In addition, you should avoid proximity to predatory animals. aggressive fish: Shrimp may seem like an attractive lunch to them.
Features of reproduction
The structure of an aquarium shrimp.
The unusual appearance of shrimp is closely related to their reproductive characteristics. The body of crustaceans is segmental, with each segment having limbs: three pairs of jaws belong to oral apparatus, and the remaining five pairs of limbs perform a direct function - moving the individual. On the body of females there are pleopods - abdominal legs on which they bear eggs; in males, the pleopods are transformed into a reproductive organ. It is easy to recognize crustaceans by sexual differences externally: females larger than males(on average, 3-5 cm), wider in the chest area, and their color is usually more saturated.
Shrimp are prone to a phenomenon called hermaphroditism, and with the onset of unfavorable conditions for reproduction, they are able to change sex!
When choosing shrimp for breeding, you must take into account the possibility of interspecific crossing: unsystematic mating of expensive breeding species leads to “degeneration” of the breed- the fry are born inconspicuous, although in this case the reproduction of shrimp does not affect the number of offspring.
Aquarium shrimp compatibility chart.
Beginners should pay attention to species such as neocardina and cherry shrimp - the most unpretentious aquarium shrimp, the reproduction of which is quite simple. But, for example, for the reproduction of offspring in Amano it is required sea water: although these shrimp are freshwater, natural conditions they migrate to a salty pond to hatch fry.
Being in comfortable conditions, crustaceans begin to reproduce quite quickly: the female becomes sexually mature by about two months; her readiness for reproduction can be determined when the eggs are clearly visible in the ovary, which is often called the “saddle” (at the junction of the cephalothorax and abdomen). The color of the eggs depends on the type of female and can vary from white to bright red.
Shrimp saddle.
By the time the eggs are ripe, the female will shed its chitin, releasing pheromones into the water that attract males. The lucky one who first discovers a partner gets the proud title of father. After fertilization, the female transfers the eggs to the under-tail region, where they adhere to the pleopods. It can take up to 2 weeks from mating to egg laying. The development of eggs takes, on average, one lunar cycle (the exact period is affected by both the water temperature and the species of shrimp). The mother takes special care of her future offspring, providing them with access to oxygen constant movements pleopod limbs and cleaning the masonry from dirt.
The fertility of a female is determined by her age and species. “Firstborns” carry only a dozen or two eggs, but the norm is adult female the amount of caviar is considered to be 1.5 - 2 times more.
Features of keeping fry
Shrimp fry are born fully formed, although very small (about 4 mm), and externally resembling their parents in color. Now the mother stops paying attention to them, and the fry begin to live own life. At first they take refuge under snags and among plants, but, having grown stronger, they become bolder, mastering the entire territory of the aquarium. Juveniles do not require special nutrition: they eat the same food as adults.
Newborn shrimp, although very small, are not much different from adults.
It is important to take care of safety: young animals often die when they get into aquarium filters. Good option in this case, a sponge filter. To protect the external and internal filters, you can purchase a fine-mesh mesh, which will need to be installed at the water intake points.
To avoid the death of the young from being eaten by fish, it is advisable to place the female in a separate container for the period from fertilization of the eggs to the relative maturation of the fry. Returning the fry to community aquarium, you don’t have to worry whether there will be enough space now: crustaceans do not claim additional “living” cubic meters, It is optimal to plant shrimp at the rate of 1-2 shrimp per liter of water.
Simple keeping conditions and unpretentiousness make shrimp farming not only exciting, but also profitable business: Having initially purchased several individuals at a price of hundreds of rubles, after a few months you can make good money by selling young animals.
Those who have once placed aquarium shrimp in their home will definitely not want to part with these creatures: their bright colors and entertaining lifestyle give real pleasure to those watching, bringing calm to the hustle and bustle of everyday life. And if this is exactly what you lack, maybe you should get some shrimp?
No matter how popular Caridina Japonica, Red Crystal and Taiwan Bee shrimp are, there will always be aesthetes in the world who can tell, show and surprise fellow hobbyists with the presence of fresh and interesting species.
In this article we will talk about domestic shrimps that live and breed in Russia. No matter how strange it may sound and no matter how northern and snowy Russia may seem, yes, indeed, shrimp live here.
But which ones exactly, the story about them is below.
Name: Freshwater Khanka shrimp
Scientific name:
Habitat: Far East(O. Khanka), b. Amur
Description: Freshwater shrimp is a small, translucent crustacean. Belongs to crustaceans (ten-legged crayfish). The body is translucent. Consists of segments: the three anterior thoracic segments are fused with the head and covered with a carapace. Its front end is elongated into a long spike. The forelimbs are transformed into jaws. Five pairs hind legs thoracic are attached to the free thoracic segments. The abdominal region consists of the abdomen, to which swimming legs - pleopods - are attached. The limbs of the last segment of the abdomen are modified into wide plates that form a tail fan. The jaws are well developed and serve for grinding food. Two pairs of mustaches, one pair very long. The claws are small, weak, but tenacious. Ten pairs of jointed legs. The shrimp's eyes are large, on short stalks. Sex can be determined when the shrimp reaches a size of 8-10 mm. Females are larger than males. In males, the first pair of abdominal legs is longer and the second pair has an additional process
Size: 3-4 cm. Males larger than females by 1-1.5 cm.
Conditions of detention: pH 6.1-7.5 KN no data GH no data t 18-28, optimal 21-24
In the aquarium, shrimp act as orderlies, removing hidden bloodworms or tubifex from the ground using their claws. Adults do not disdain detritus; they eat dead fish and rotting plant leaves. Shrimp need clean, oxygen-rich water. Active during the day. Tendencies towards cannibalism.
Breeding: Sexual maturity is reached at approximately 1 year of age. The female lays up to 200 eggs. The development time of the eggs depends on the water temperature: 2-4 weeks. The hatching larvae go through three stages of development before turning into tiny shrimp. Juvenile shrimp are fed with yeast, then with “live dust”, small worms, fish, meat, etc. Juveniles are sensitive to water quality.

Shrimp are extremely interesting and useful inhabitants any aquarium. Unpretentiousness to water quality and living conditions makes these freshwater creatures good choice for the novice aquarist, while the professional will be interested in the variety of forms and the possibility of flexible selection. Shrimp in a fish aquarium form a diverse and functional ecosystem, however, for its stability and prosperity, it will be necessary to carefully monitor the compatibility of all members of such an aquatic community.
The plight of peace-loving shrimp
Shrimp shelters can be purchased at the store or made yourself.
IN natural environment Shrimp occupy the lowest level of the food pyramid, so it is quite difficult to “make friends” with fish. This process is also characterized by the fact that keeping shrimp in an aquarium with fish is complicated by the omnivorous nature of the latter. Even small species they instinctively try to swallow any creatures smaller than themselves, even if they are not part of their traditional diet. Therefore, the main defense of aquatic arthropods is their size: those who want to feast on a small crustacean will quickly abandon their intentions if it approaches them in size.
It is worth remembering that small “newborn” shrimp will be pursued even by those species that can get along well with adults. Therefore, if the owner of an aquarium is interested in the high survival rate of the young, they should definitely be placed in a “nursery”.
Another important condition is to ensure good compatibility shrimp in an aquarium with fish is to create the most complex landscape where tiny arthropods could hide and go about their daily business. Any means are suitable for this: stones, plants, deep soil, artificial shelters, grottoes, corals, etc. But creating the opportunity to hide is only an auxiliary measure; first of all, you still need to look at what kind of fish you can keep shrimp with. Even if tiny crustaceans are able to run and hide, then the constant expectation of an attack will lead to severe chronic stress and subsequent death.
Not every fish will escape from the macrobrachium Rosenberg shrimp unharmed.
But even among peace-loving freshwater arthropods there are sometimes atypical aggressive species, which can not only stand up for themselves, but also attack small and medium-sized fish themselves. Thus, various filter-feeding shrimps do not attack other inhabitants of the aquarium, but in case of danger they take a protective pose and give the enemy a worthy rebuff. But representatives of the genus Macrobrachimu are precisely those aquarium shrimp whose compatibility with fish tends to zero: having an impressive size (up to 30 cm), they will sooner or later eat all their smaller neighbors in the aquarium. Those who cannot be eaten will still not escape unharmed, since at night the freshwater giants will certainly shred their fins and tails (veiled fish will be especially unlucky in this regard).
If the shrimp have lived long enough, then sooner or later their remains will definitely appear at the bottom. But you shouldn’t blame the other inhabitants of the aquarium for this, since the imaginary “corpses”, upon closer examination, will simply turn out to be a shell that was thrown off during the molting process. By the way, you should not immediately remove them from the aquarium, since by dissolving, the old skeleton increases the concentration of salts necessary for the normal development of young arthropods.
Summarizing all of the above, the conclusion suggests itself that it is possible to keep shrimp and fish in an aquarium, but you should select arthropods for the fish, and not vice versa.
Good neighbors
Neons are excellent neighbors for all types of shrimp.
First of all, it is worth saying that it is impossible to give a definite answer to the question of what fish shrimp get along with. There is no universal compatibility table for shrimp, since this parameter depends on many factors: first of all, the size of the aquarium, its level of population, including plants, landscape, temperature regime, abundance of feeding and even individual characteristics each individual aquatic inhabitant. That's why in this matter you can only rely on personal subjective experience and the experience of other aquarists.
If we talk about specific types, then shrimps find it best in an aquarium with fish common language with various "orderlies" aquatic environment. For example, Siamese algae eaters can live with rili shrimp. And not only the Siamese algae eater and shrimp are compatible in the same environment; all representatives of the genus crossocheilus (relatives of the above-mentioned algae eaters) get along well with unpretentious arthropods. Shrimp and ampullaria coexist well, simply living in different worlds and unaware of each other's existence. Also, do not forget about a variety of catfish: the compatibility of catfish and shrimp is well known to aquarists, because these bottom fish They have a very peaceful character.
At favorable conditions Ampullaria are very prolific, which can lead an aquarium to a real disaster. But if a small population of shrimp is kept with the snails, then the arthropods will destroy almost all the small ampullaria, maintaining the natural balance of the ecosystem.
Another large category of fish with which shrimp get along in the aquarium includes a variety of small, non-aggressive species. The compatibility of neons and shrimp can be estimated at almost 100%. The group of ideal fish for shrimpers also includes dwarf guppies, zebrafish, microrasboras, microplates, neon irises and parotocinclus.
Conditional table of compatibility of shrimps with aquarium fish.
Bad neighbors
Majority aquarium fish They are neutral towards their arthropod neighbors and attack them only under certain circumstances. Such a provoking factor may be elevated temperature water, mating season, starvation or just an unfortunate coincidence. Thus, the compatibility of shrimp and swordtails (as well as most other viviparous species) can range from neutral ignoring to aggressive extermination. This intermediate category also includes large platies, barbs, brochis, girinocheilus, cardinals and rhodostomus.
Despite the fact that cockerels are very aggressive towards shrimp, there are examples of their peaceful coexistence.
Of course, there are also species with which it is simply impossible for arthropods to live peacefully with them. Most often, these are traditional aggressors and predators, such as rooster fish: shrimp and a rooster will not live even a day in the same aquarium, since the entire flock of unfortunate crustaceans will be exterminated in the very first hours of their acquaintance. The same deplorable indicator of compatibility of shrimp and gourami, cichlids (including discus fish), and various goldfish.
Once again, it is worth noting that the division of fish into three categories of compatibility is quite arbitrary, since V different conditions the nature of interspecies relationships can vary greatly. For example, it is not uncommon for aggressive cichlids and characins to completely ignore large schools. Before carrying out the mass “addition” of certain shrimps into the aquarium, it is recommended to add a couple of test specimens, which will make it possible to study the reaction of the fish to new neighbors. And of course, we should not forget about dense vegetation, the presence of which is beneficial for these tiny arthropods.
For the convenience of our guests and regular users, we have compiled a catalog of popular types of aquarium shrimp. This list was compiled in alphabetical order, with a photo and a link to a single shrimp. Also, if necessary, you can always refer to the section of the site.
Not so long ago, in 2006, thanks to new research on Japanese shrimp, it was established that the Caridina japonica shrimp (discovered and described in 1892) and the Caridina multidentata shrimp (previously described in 1860) are the same species. Thus, since 2006, the name of the Amano shrimp has been officially changed to “Caridina multidentata”.
Famous aquascaper and creator of the so-called “ natural aquariums» Takashi Amano was the first to use these shrimp to control algae in his herbal aquariums.
Finding them amazing ability to eat algae, he immediately ordered several thousand shrimp from a local livestock merchant. Since the 1980s, aquarists began to call it “Amano”.
Babaulti shrimp have a bright green body. Green babaulti shrimp have a special feature: they are able to change the color of their body, becoming either green, light brown or red. The color depends on what mood the animal is in, how it eats, and in what conditions it lives.
It is also worth noting that it is quite difficult to find well-painted Babaulti on sale, as in the pictures. Often these are tiny, pale green shrimp.
In addition, there are many color morphs of Babaulti: brown, orange and red varieties.
Cherry or Cherry shrimp is a species of shrimp selectively bred in Germany, obtained through a long process of crossing wild shrimp Neocaridina Heteropoda.
An aquarium with shrimp of this species should be well planted with plants on which Cherry Shrimp spend a lot of their time just sitting, and be sure to have shelters in which they hide for protection, especially after molting.
An almost transparent shrimp with dark transverse stripes along the body and light specks. Rostrum with straight upper and slightly convex lower margin. The single-toothed end of the beak, directed straight forward, protrudes slightly beyond the anterior edge of the scaphocerites. Of the three antennal whips of the 1st pair, two are fused together with 6-7 segments. Has small claws. The color of shrimp largely depends on the color of the food, as well as the shade of the soil. The size of the shrimp is about 5 cm.
In 1993, the Japanese Hisayasu Suzuki, while breeding shrimp of the classic black color, accidentally received an unusual shrimp - a red shrimp. After some time, 3 more of these shrimp appeared. Deciding to fix the red gene, he began selecting and crossing shrimp with red stripes.
By 1996, the breeder had several thousand red and white striped shrimp, which quickly gained popularity and love among shrimp lovers. Hisayasu Suzuki patented their name "Crystal Red".
Genus Macrobrachium - Macrobrachium.Shrimp from the genus Macrobrachium have been used in the aquarium hobby for a relatively long time. All members of the family are not peaceful. Some representatives of the genus are distinguished by their respectable size (up to 15-20 cm) and are used in gastronomy (in particular, Macrobrachium rosenbergi, which is successfully bred in industrial scale on special farms).
Fortunately for nature lovers, among the representatives of the genus there are many relatively compact creatures suitable for cultivation in home aquariums. These primarily include shrimp Macrobrachium nipponense - River, eastern Japanese shrimp. In addition to Macrobrachium nipponense, other representatives of the genus are also kept in aquariums.
Rili shrimp (Neocaridina heteropoda sp. Rili) is the fruit of selection, bred in 1996 in Taiwan, Hisayasu Suzuki - a Japanese breeder, the one who gave the world the magnificent crystal shrimp.
Here are the approximate conditions that are most favorable for keeping and breeding rili shrimp: aquarium - from 10 liters, water temperature - 22-28 degrees, pH 6.0 to 8.0 with soft and medium hard water. It is advisable to keep shrimp in a group of 10+++ individuals; the aquarium should have rich aquatic flora - the shrimp should have shelter in the form of plants and mosses.
Glass shrimp live relatively short - 1 - 1.5 years and grow up to 4 cm. They are extremely easy to maintain and care for. Ghost shrimp, unlike many other relatives, are not pretentious to soft and slightly acidic water. Water parameters for their maintenance: temperature: 22-27 C, pH - 6.5-7.5, kH 5-8; gH 5-8, dH - 4-8; TDS - 120-180. Weekly water changes are required. Aeration and water filtration are also necessary. You need to create places in the aquarium where ghosts can hide. This could be snags, thickets of plants, a pile of stones, etc.
The habitat of the Cardinal shrimp is the rocky areas of the lake on the island of Sulawesi in Indonesia. Its size is on average one and a half centimeters. They are very active in obtaining food from bottom stones and algae, as well as from snail shells from their native island. Therefore, in their home there should be an abundance of such decorative elements How aquarium plants, stones, aquarium driftwood and other objects overgrown with algae. The color intensity of the Cardinal shrimp has nothing to do with gender, age, emotional or physical condition individuals. The body color is various shades of cherry and red, contrasting attractively on the sides with white spots that may be edged in blue. Characteristic sign- white front paws, which the crustacean quickly and amusingly moves while getting food.
The filter feeder shrimp, unlike other shrimps, is clumsy, if I may say so, clumsy. She will not jump around like a flea throughout the aquarium and the reason for this is the way she feeds. The filter-feeding shrimp feeds by means of fan-shaped cilia, which are located on its claws. With them, the shrimp catches “goodies in the wind” - microorganisms, small particles of fish food, plant remains, etc. To do this, the shrimp climbs to the most “blown place” - the place where the flow from the filter is as intense as possible and spreads its fans there. As soon as the food has entered the fan, it is brought to the mouth. This is actually why the filter feeder shrimp has a certain clumsiness - its heavy body and tenacious legs are adapted to stand spread apart with the flow.
The Black Tiger Shrimp, also known as the Black Diamond Shrimp, mainly in Japan, is becoming a very popular species among modern shrimp breeders. This species was selectively bred from the common Tiger Prawn, where, over a long period of time, specimens with the most black stripes were selected for crossing, in the end, the selection gave the long-awaited result and the shrimp became completely black.
There are two varieties of Black Tiger Prawn - one with black eyes and the other with orange eyes. Moreover, those with orange eyes are valued much higher than their black-eyed relatives.
