Freshwater Shrimp

More and more aquarists want to keep shrimp lately: it is interesting to watch them, they are unpretentious, and any fish can envy the abundance of colors. The three front thoracic segments of the shrimp are fused with the head, they are securely covered with a protective shell.

A characteristic feature of the appearance of shrimp are whiskers, mandibles and jaws. Thanks to abdominal legs (pleopods), shrimps swim, and with their help they snatch out small pieces of dry food and aquatic plants from the water.

On walking legs, shrimps move along the bottom, looking for leftover food. In fact, shrimps only seem clumsy: they quickly become familiar in an aquarium, it is rather difficult to catch them, but it is very interesting to watch their pack life.

Shrimps can be called universal sweepers, they are non-conflicting, they get along perfectly with small and medium-sized peaceful fishes. Freshwater shrimp can also be contained in special tanks – shrimp; they react to the chemical composition of water more strongly, since they have a higher sensitivity than fish.

For the maintenance of freshwater shrimp will need an aquarium, a volume of 50-80 liters. In a small tank, it will be more difficult to maintain the biobalance, and in a large capacity the shrimps will simply be lost against the backdrop of the scenery.

If you keep shrimp with fish – the volume of the aquarium should be larger. In the aquarium should be present snags, plants and other shelters in which pets can hide.

Ideally, no more than one shrimp should be planted for 1-2 liters of aquarium water, their size plays a big role here. Often, freshwater shrimp perfectly feel at a temperature of 20-27 degrees, but above 30 degrees it should not rise. If the water is cool, degrees 15, the metabolism of shrimp will slow down, they will cease to multiply, become inert and sluggish.

As for the pH of the water, it can vary from 6.5 to 7.5, if the acidity is lower, it will contribute to the destruction of the shell of shrimp. Do not allow a sharp temperature difference: 6-7 degrees of difference are fatal for these individuals.

Also, shrimp die if the water contains copper. Shrimps are inquisitive creatures, they love to explore different slots and often cannot get out of them and die, which is why the filter intake pipe must be closed in the aquarium, it is advisable to use internal filters without plastic flasks and the background is not desirable to use volumetric. The compressor should be turned on in the aquarium around the clock, as the crustaceans are sensitive to oxygen levels.

From time to time siphon the ground (its thickness should be 4-5 centimeters).

It is worth remembering that shrimps grow at the moment of dropping their cover, at this moment they remain defenseless and will spend some time in shelters (old plastic tubes, stones with large holes, thickets of plants). The old chitinous cover from the aquarium should not be thrown away for some time – some shrimps eat it and quickly build up a new shell.

Shrimp food can be different: you can buy specialized food, you can give aquarium algae and fish food. Feed shrimp little by little, remove leftover food.

If shrimps live in your pond, you need to change the water more often, because eating crustaceans is quite a lot. Be careful and quarantine a new fish, shrimp or even a plant in the tank.

Plants need at least a day to keep in a separate container and often change the water in order to reduce the concentration of harmful chemicals.

Snowflake (Neocaridina white). One of the decorative varieties, it is difficult to confuse with the other, because it has a snow-white color, even the eggs of this crustacean are pure white. The snowflake is a relative of the blue pearl shrimp, both species were bred in Germany, so its color is the result of a long work of breeders.

Saku and the male snowflake can be distinguished by size: the female has a bright color, larger, and the shell on the abdomen is somewhat wider.

Harlequin (Car. Natural habitat of freshwater shrimp is Indonesia.

This is one of the smallest species of shrimp, they are quite shy. It lives and eats at the expense of a freshwater sponge – with its help it eats algae and feed particles. Sex differences of shrimp are poorly expressed, since the color of males and females is the same.

Harlequin is variegated, mixed, dominated by white, black and red. Harlequin shrimp often hide in shelters and adapt to new environments for a long time.

Khankai Shrimp (Leander Modestus). The natural habitat of shrimp is Amur estuary (Far East). Shrimps grow up to 3-5 cm, males are somewhat larger than females.

Something these arthropods resemble crayfish. They have weak and small claws, long mustaches, convex beak, body transparent – pale-gray-brown.

These shrimps are excellent attendants, hardy, active, not conflict.

Cardinal. The cardinal is a very beautiful type of shrimp, the color can vary from rich red to light pink with white dots.

Only suitable for experienced aquarists. The natural habitat of shrimp is Sulawesi Island (Indonesia). In the lake, the cardinal lives among the stones, where he is looking for food.

The color saturation can vary, sometimes the white points on the body of the shrimp have a blue outline. Shrimps have white front legs – with their help representatives of this species can move quickly.

Bee (Red bee). Bee shrimp is a direct relative of crystal red shrimp that was first discovered by a breeder from Japan, since it has appeared in many aquariums.

Bee shrimp prefers weakly acidic water, it is sensitive to pollution and changes in water indicators. Often the bee shrimp (with black stripes) is crossed with Crystal Red.

Ninja Shrimp (Ninja Shrimp). This shrimp with a peculiar name can quickly change colors and perfectly mastered the “art of camouflage.” It is also called honey or Christmas shrimp, salt water is required for this species to breed.

Natural habitats are the waters of Asia, we immediately note that to catch it in the wild is very problematic. Color varies depending on the habitat: the shrimp can rapidly change its color from red to yellow, from blue to black or brown – it is not difficult for it.

They have high ability to imitate, they easily adapt to the environment.

Japanese shrimp (Caridina japonica). These shrimps belong to the family of macrobranchies, they prefer to live in streams and rivers with clean water at home.

They grow up to 6-8 centimeters, their characteristic features are orange claws, a black stroke on the back with a white border, and on walking legs – white socks. The body of the shrimp is brownish, translucent.

This type of unpretentious, but with sedentary inhabitants of aquariums (small) get along poorly, often fighting.

Ringed shrimp (Macrobrachium assamense). Its natural habitat are water bodies of Nepal, Bangladesh.

Males significantly exceed smok in size, they grow up to 8 cm, while females only up to 6. Ringed shrimps have a rich marble brown or gray pattern, on their claws are red-black rings – hence the name of the species. It is not desirable to keep several males together – they will conflict, also small fish or crustaceans are not suitable as neighbors.

Striped dlinokleshnevaya shrimp (Macrobrachium carcinus). It lives in rivers and streams of America, grows to 35 cm, large specimens often conflict over the territory and do not like their relatives, there is a tendency to cannibalism.

The abdomen and body are colored with yellow-brown longitudinal stripes, strong claws, blue or brown.

Black tiger shrimp (Penaeus monodon). Black shrimp is very beautiful, with bright orange or black eyes (the first kind is valued more).

These shrimps are very sensitive to water parameters, bred as a result of long selection, not suitable for beginners, since their breeding requires considerable effort.

Amano (Caridina multidentata). This shrimp is often found in aquariums; it owes its name to the breeder Takashi Amano.

In the wild, shrimps of this species live in Japan, in the south of the country. The color of crustaceans depends on what they eat: it can be reddish or transparent green, often they are almost transparent.

Black lines and dots are scattered around the body, grow to 3-6 cm, females are larger.

Thailand glass shrimp (Macrobrachium lanchesteri, Glass shrimp). This species of crustaceans lives in the rivers of Asia, keeps near the coast.

Representatives of this species are very territorial, like to dig holes in the ground. They grow up to 8 centimeters, the color is transparent, a black stripe runs along the back. Males are larger, their claws are more elongated, with a scalp, females seem more stocky.

Live no more than 3 years.

Whole freshwater shrimp several hundred species, we have described only the main ones.
