Freshwater Shrimp: Care, Diet, and Breeding Essentials

Freshwater Shrimp

Freshwater Shrimp Facts & Overview

Freshwater shrimp are intriguing amphipod family members, often mistaken for shrimps, sharing lineage with the marine sand hopper. These versatile denizens dwell both in warm and chilly waters globally, reaching incredible depths of up to 16,000 feet. One remarkable example is the Malaysian Prawn (Macrobrachium Rosenbergii), a vital part of the freshwater shrimp industry from an environmental and financial standpoint. We further investigate these impressive beings’ origin, adult size, life expectancy, and availability.


Originally from the vast underwaters of Earth, freshwater shrimps are found throughout the globe. The species Atya scabra has been spotted in rocky river beds, clean streams, and locations boasting fast water currents and high dissolved oxygen levels. Taiwan, on the other hand, is home to the famous Neocaridina davidi, contributing significantly to the field of freshwater shrimp developmental biology.

Adult Size & Life Expectancy

The size variations among freshwater shrimp are honestly astonishing. While some individuals reach only about 1.96 inches, like the endangered California freshwater shrimp (Syncaris pacifica), others like the Malaysian Prawn exhibit a more imposing size.

As for life expectancy, various factors such as diet, habitat, and care can influence it. Generally, regular monitoring of their freshwater shrimp tank and diet conditions aids in enhancing their lifespan.


Despite the endangered status of some species like the California freshwater shrimp, others such as Atya scabra and Macrobrachium rosenbergii are available and used widely in commercial productions, promoting sustainable farming practices.

Freshwater Shrimp Appearance & Behavior

A closer look at the freshwater shrimp reveals further intriguing aspects like their unique colors, patterns, sizes and typical behavior.

Colors, Patterns, and Size

Diversifying aquarium aesthetics, freshwater shrimp colors range from subtle shades of transparent to vibrant red, yellow, and blue hues. The Syncaris pacifica is more petite, with the females slightly larger than the males and the maximum length measuring 1.96 inches. Their wrinkly bodies and robust builds are beautifully designed for their scavenger lifestyle. Interestingly, a freshwater shrimp’s rostrum or “beak” sports a square shape compared to the pointed version in saltwater species.

Typical Behavior

Scavenging at the bottom of their habitats, freshwater shrimps spend most of their time feeding. Their diet is surprisingly rich in animal protein, with evidence pointing towards predation on other aquatic organisms.

Freshwater Shrimp Tank & Water Requirements

Understanding their tank and water requirements is pivotal if freshwater shrimp catch your eye for your next aquarium addition. Conditions must imitate their natural habitat to ensure a healthy and comfortable environment.

Habitat and Tank Requirements

An Atya scabra, for instance, prospers in water currents and high dissolved oxygen levels. Hence, setting up a water filter for strong water currents and an air stone for oxygen supply will make an ideal freshwater shrimp tank.

Water Conditions

Given their diverse origins, freshwater shrimp temperature preferences vary. They can thrive in both cold and warm waters (depending on the species), though a well-regulated water temperature is imperative. An optimal diet and fine-tuned water pH level are also keys to a thriving freshwater shrimp population. Keeping in mind their inherent predation tendencies can help create a balanced ecosystem.

Freshwater Shrimp Care & Diet

Paying heed to their diet and general care is crucial to keep your freshwater shrimp healthy. Let’s take an in-depth look at feeding, caring, and common problems encountered in freshwater shrimp-keeping.

Diet and Feeding

Surprisingly, these cute scavengers are carnivorous! A shrimp’s diet includes a considerable amount of animal protein and they have even been documented preying on other aquatic organisms. Nutritionally speaking, freshwater shrimp like the raw iqf by BD is a protein powerhouse, providing 21g of protein and an optimal 90 calories per 112g serving. This lean, white, lobster-like flesh is also low in fat and carbohydrates, making it a healthy dietary inclusion.

General Care

Freshwater shrimp are generally low-maintenance. A well-maintained aquarium with suitable water currents, high dissolved oxygen levels, and proper nutrient supply compliments their lifestyle well. Ensure water parameters like pH, hardness, and freshwater shrimp temperature remain within acceptable ranges.

Common Problems

Despite their hardy nature, freshwater shrimps can potentially face issues like low oxygen levels, improper dietary supply, or inappropriate freshwater shrimp tank mates. These factors can lead to stress, disease, or even death, so regular monitoring and care are pivotal.

Is a Freshwater Shrimp Dangerous?

Contrary to misconceptions, freshwater shrimps don’t pose any significant threat to human beings or their fellow inhabitants. That being said, remember they are carnivorous – their predation on other aquatic organisms is well-documented.
