Giant freshwater shrimp

One of the most fascinating aquarium animals is the giant freshwater shrimp. These remarkable crustaceans, which are frequently called "Macrobrachium," can reach enormously impressive sizes. They give your tank a dash of exotica with their long, spiny legs and big claws. They are not only an eye-catching addition, but they also display fascinating behaviors that will enthrall anyone who enjoys aquatic life.

The fact that giant freshwater shrimp are active is one of their most fascinating characteristics. These shrimp, in contrast to certain more sedentary aquarium inhabitants, are always moving, searching for food and taking in their surroundings. This renders them immensely captivating to observe. Their interactions with their environment and expression of their innate instincts give your aquarium a dynamic touch.

For aquarium enthusiasts, raising giant freshwater shrimp can be a fulfilling challenge. To flourish, they need certain water parameters and an environment in tanks that is well-organized. However, you can create an environment that will support the growth of these shrimp with a little planning and research. Their presence can also assist you in creating an aquatic setup that is livelier and more varied.

To put it briefly, aquarium enthusiasts can enjoy the beauty and excitement of giant freshwater shrimp. They will undoubtedly add something special to your aquatic collection, whether it’s because of their eye-catching appearance or their captivating behavior. These shrimp have the potential to become your new favorite aquarium inhabitants if you’re willing to take on the challenge.

Appearance and natural habitat

One of the most well-known and common members of the crustacean family is the giant shrimp, sometimes referred to as the Rosenberg shrimp. Although it is found naturally in the reservoirs of Malaysia, New Guinea, Vietnam, Australia, and India, it has recently been cultivated almost everywhere on Earth.

Given that an adult shrimp’s size is approximately 32 cm or greater and that its weight category averages 250 g, the name "giant shrimp" is aptly justified. As a result, a fairly large and roomy artificial reservoir will be needed to house such a mollusk.

A giant shrimp is distinguished by its long, black-stained claws, and most of the time, one limb is noticeably shorter than the other. Notable is also the fact that females lack claws, while males have them exclusively.

A giant shrimp’s claws serve several practical purposes:

• food mining;
• orientation in water space, the ability to feel the approach of a predator or changes in the parameters of the aquatic environment;
• a means of combating opponents and relatives in the battle for the territory, attention of the female, upholding of leadership positions;
• Tool for capture and adhere to a female during mating.

The remarkable bright orange mustache of Rosenberg shrimp is another unusual characteristic. Its length is several times longer than the mollusk’s whole body. This crustacean also has a striking red nose that is easily noticeable on its head.

The enormous shrimp may have a distinct color. Representatives are typically found in nature with males that are brownish or blue in color and females that are silvery-gray in color. Colorless and nearly transparent specimens are much less common; as they mature, they do, however, take on shades of camouflage that are only mildly expressed.

Furthermore, some scientists assert that the giant shrimp’s color can vary based on the color of the soil in its habitat, although there is currently insufficient evidence to support this theory.

Features of behavior in the natural environment and the lifestyle of the giant shrimp

Giant shrimp are naturally predatory animals; they clearly exhibit a strong hunting instinct, even though they do not detest plant food. These members of the crustacean family have a primarily nocturnal lifestyle, preferring to sleep in a quiet, shaded area during the day and to hunt and search for food as dusk approaches.

The mollusk known as the rosenberg shrimp is solitary by nature and is constantly vigilant, protecting its area from intruders and unwanted visitors. In addition, in contrast to the majority of other crustaceans, a member of the dominant sex will engage in territorial disputes not only with other males but also with females, unless the mating season has begun and they intend to procreate.

However, this is limited to a fight involving two men. Giant shrimp live in strange families in which there is one male and several females. In this lifestyle, the mollusks live in harmony, tend to their young, and the males defend not only their small "harem" but also their territorial area from any threats.

Massive shrimp are amazing. These mollusks constantly dust themselves and clear away debris. But the real reason for this habit isn’t so much a love of cleanliness as it is the sensitivity to different kinds of pollution that the Rosenberg shrimp needs for protection from potential predators, orientation in space, and food hunting.

It’s not easy to keep a giant shrimp at home, but it is possible if you really want to. Aquarium enthusiasts observe that these crustaceans not only have stunning looks that adorn the aquarium, but they also have hilarious habits that are fascinating to watch.

The aquarist will need to make every effort to provide the conditions that the Rosenberg shrimp needs in order for it to live a long time, remain active, and feel comfortable. Expert advice states that these conditions should be as similar to the shrimp’s natural habitat as feasible.

Aquarium requirements

Giant shrimp should be kept in very large, roomy aquariums. A large bottom area pool made of plastic or concrete would be the best option. Even though the tank’s volume and wall height aren’t as crucial, the shrimp still need enough room to live comfortably and in privacy.

Tight quarters and overcrowding in an artificial reservoir can trigger aggressive outbursts, family fights, and other conflict situations that frequently result in severe trauma injuries or even the death of enormous shrimp.

These crustaceans have a tendency to escape the tank because they are so active and mobile. However, giant shrimp have a very limited lifespan in the absence of an aquatic environment.

Because of this, seasoned aquarium keepers highly advise protecting your pets’ safety by covering the artificial reservoir with clear protective glass, which enables you to prevent negative consequences.

Since giant shrimps are only acclimated to tropical climates, the aquarium will require an additional heater as well as a filter. Making sure the artificial reservoir’s current isn’t too strong is also essential. The Rosenberg shrimp is a creature that prefers mild, muted lighting. The best amount of daylight occurs during the day between 10 and 12 hours.

Dark river sand will be the perfect soil for this representative of the crustacean family. It is ideal if the soil has terraces and depressions that let you mimic nearly natural conditions.

Parameters of the aquatic environment

The giant shrimp finds it very difficult to adapt to changes in the climate because it is so sensitive to the habitat and its parameters. As a result, aquarists must closely watch over the tank’s water parameters’ maintenance:

• temperature – from +24° to +28°C;
• hardness – from 5° to 10°;
• acidity – from 6.5 to 8.5.

It is important to monitor the temperature regime in particular. The shrimp first cease to feed, become lethargic, and lose their ability to reproduce when the water temperature falls below +20° C. They eventually perish when the temperature falls below +13°. Purchasing a heating appliance with automated control and regulation is advised by experts to maintain the ideal temperature regime.

The Rosenberg shrimp also require a higher oxygen content. However, it has a very bad reaction to nitrites and nitrates. The mollusk’s size, color, and behavior change as their levels rise. Special tests are available at most pet stores to determine the presence of the above elements in the aquatic environment.

Aquarium decoration

When designing an artificial reservoir that will be used to house and grow Rosenberg shrimp, it is important to make sure that the tank has an adequate amount of sturdy shelters. Ordinary stones, driftwood, algal thickets, green obsessions, and ceramic castles, caverns, and grottoes are all ideal for these uses.

Giant shrimp require these isolated areas to survive. This mollusk actually molts frequently, exchanging its old shell for a new one. Since cannibalism among crustaceans is a common occurrence, the shrimp becomes extremely vulnerable and defenseless during this time, not only to predators but even to other members of its own kind.

When it comes to adding vegetation to the aquarium, keep in mind that large shrimp like to eat the leaf plates of aquatic and above-water plants, which can harm or even kill the plants. Thus, the best choice would be crops that are inedible to shrimp, like cryptocoryne or ophiopogon (snakebeard).

Additionally, you can divert crustaceans’ attention from green areas by feeding them leaf plates of nettle, burdock, dandelion, lettuce, and spinach on occasion. You can also use small pieces of fresh fruit or vegetables. This food will be enjoyed by the shrimp, who will even prefer it to the greenery in the aquarium. If these methods prove ineffective, it may be necessary to remove the plant crops from the aquarium and replace them with artificial plants that serve as both decorations and barriers.

Rosenberg shrimp can, with some difficulty, adapt to other aspects of the aquatic environment and living conditions, but this greatly shortens their lifespan, as demonstrated by the results of scientific research and testing.

The enormous shrimp can survive for up to five years or longer in an artificial environment if you heed the advice given above.

Massive freshwater shrimp are a fascinating addition that are useful and aesthetically pleasing to any aquarium. By scavenging for leftover food and organic debris, these magnificent creatures contribute significantly to the upkeep of a healthy tank environment in addition to being aesthetically stunning in size and vivid colors. Aquarists can create a thriving habitat that benefits shrimp and the entire aquatic ecosystem by understanding their needs and behaviors.

Feeding features

As a omnivore, rosenberg shrimp typically don’t have any nutritional issues at home. Crustaceans gladly consume dry, frozen, or natural food. It is advised to give the mollusks tubifex, daphnia, etc. on a regular basis. After all, giant shrimp require live, high-protein prey in order to survive.

Chopped fruits and vegetables, greens that have been pre-treated in boiling water, and plant leaf plates will all be enjoyed by Rosenberg shrimp.

Live food should make up a significant portion of the menu, but a combination of plant and animal foods is advised to maintain an optimally balanced diet.

Furthermore, ready-made food made especially for feeding crustaceans is available in pet stores. Feeding the shrimp once every one to two days is advised. Try to measure out how much food to give them so they can eat it right away and not let it sink to the bottom. If not, you will need to clean the soil and siphon it (learn more about how to siphon the soil in an aquarium).

Reproduction in an artificial environment

It is possible to reproduce giant shrimp under aquarium conditions, but it will take some time and work. There are three steps you must take in order to produce healthy offspring:

1. Preparatory. During this time, several females are placed in a separate tank with a temperature regime of about +22°C and kept there for 3 weeks. During this time, it is recommended to feed the females abundantly with high-quality, live, vitaminized food.
2. Reproduction. After 3-4 weeks of preparation, one male is placed in a container with several females. In most cases, eggs are formed after a few days. After this, the father is sent back, and the females take care of the eggs, independently separating live eggs from dead ones.
3. Larval stage. The larvae begin to feed on the 2nd day from the moment of their birth, using brine shrimp for this purpose. When they reach one week of age, add minced fish and chopped egg yolk to their diet. In general, the process of shrimp formation from a larva involves going through 12 stages. It is recommended to keep young shrimp in a separate tank to avoid cannibalism. It is best to place them in a common aquarium when they reach sexual maturity – at the age of about 3-4 months.

An intriguing and unique aquarium resident are giant shrimp. The majority of seasoned aquarists are quite proud of their original pets with an exotic appearance and unusual habits, even though maintaining them takes some work.
