Shrimp play an important role in various ecosystems, from the wild to aquariums. Understanding what do shrimp eat is crucial for anyone interested in shrimp care or the dynamics of aquatic habitats.
These small creatures are scavengers, feeding on a variety of organic materials, but their diet can vary significantly depending on their environment. In the wild, shrimp consume plankton, detritus, and decomposing plant matter, helping to maintain the balance of their ecosystems.
Meanwhile, in aquariums, shrimp are often fed specialized foods to meet their nutritional needs. Additionally, shrimp play an important part in the food chain, serving as both prey and cleaner organisms.
This guide will provide an in-depth look at shrimp’s diet across different environments, from the ocean and wild habitats to aquarium settings, as well as during breeding. Understanding their dietary habits is key to ensuring they thrive in both natural and controlled environments.

What Do Shrimp Eat in the Wild?
In the wild, shrimp’s diet is influenced by their habitat and the availability of food sources. Their role as scavengers allows them to consume a wide variety of organic matter, contributing to the health of aquatic ecosystems.
Below are the main components of a shrimp’s diet in natural environments.
1. Plankton
Plankton, both phytoplankton (microscopic plants) and zooplankton (tiny animals), forms a significant part of a shrimp’s diet in the wild. Shrimp filter these organisms from the water, which provides them with essential nutrients.
2. Detritus
Detritus refers to decomposing plant and animal matter that sinks to the bottom of water bodies. Shrimp consume this organic matter, breaking it down and helping recycle nutrients back into the ecosystem.
3. Algae
Shrimp feed on various types of algae that grow on surfaces such as rocks, plants, or substrates. Algae is an important source of energy and nutrients, especially in freshwater environments.
4. Small Invertebrates
Shrimp may also consume small invertebrates such as tiny worms, mollusks, or other microscopic creatures that share their habitat. These small organisms supplement the shrimp’s protein intake.
5. Decomposing Plant Matter
In many habitats, shrimp feed on decomposing leaves, wood, and other plant material. This helps in the breakdown of organic matter, making nutrients available for other organisms in the ecosystem.
6. Bacteria
In certain cases, shrimp will consume bacteria that grow on decaying matter or surfaces in their habitat. This additional food source helps sustain them in nutrient-poor environments.

What Do Shrimp Eat in Aquariums?
In aquarium settings, shrimp’s diet is primarily influenced by the type of shrimp species and the environment created within the tank. Since natural food sources like plankton and detritus are not as readily available, it’s important to provide a balanced diet to ensure their health.
Below are the key food sources for shrimp in aquariums.
1. Commercial Shrimp Pellets
Commercial shrimp pellets are specially formulated to provide the necessary nutrients, including protein, vitamins, and minerals, that shrimp need to thrive in aquariums. These pellets are one of the most common foods for shrimp in tank environments (source: Aquatic Arts).
2. Algae Wafers
Algae wafers are a popular food choice for aquarium shrimp as they mimic natural algae sources that shrimp feed on in the wild. These wafers provide shrimp with essential carbohydrates and are an easy way to supplement their diet.
3. Fresh Vegetables
Shrimp also benefit from fresh vegetables such as spinach, zucchini, and carrots. These vegetables provide fiber, vitamins, and minerals that help support shrimp health and molting (source: The Shrimp Farm).
4. Live Plants
Live plants in aquariums can serve as both hiding spots and a natural food source for shrimp. They graze on algae and biofilm that grow on the surfaces of plants, contributing to their diet and maintaining tank cleanliness.
5. Protein-rich Foods
During breeding or molting periods, shrimp require higher protein intake. Foods such as bloodworms, brine shrimp, or daphnia are great sources of protein that aid in growth and reproduction.
6. Calcium Supplements
Calcium is crucial for shrimp to maintain healthy exoskeletons. In aquariums, calcium supplements in the form of crushed coral or specially designed shrimp foods can help ensure the shrimp’s shells stay strong (source: Shrimp King).
7. Biofilm and Algae Growth
Shrimp naturally graze on biofilm and algae that accumulate in aquariums. This food source is crucial for their survival in tanks, as it mimics the grazing behavior they exhibit in the wild.
What Do Shrimp Eat in the Ocean?
In the ocean, shrimp’s diet is highly varied, depending on their species and the type of environment they inhabit. They play a vital role in the marine food web, serving both as prey for larger predators and as scavengers, cleaning up the ocean floor by feeding on detritus and small organisms.
Below are the key food sources for shrimp in ocean ecosystems.
1. Plankton
Plankton, including both zooplankton (small animals) and phytoplankton (microscopic plants), forms the primary food source for many shrimp species in the ocean. These tiny organisms are filtered from the water, providing essential nutrients.
2. Detritus
Shrimp in the ocean often feed on detritus, which includes decomposing plant and animal matter. By consuming detritus, shrimp help recycle nutrients back into the ecosystem, promoting a balanced marine environment.
3. Algae
Like freshwater shrimp, ocean shrimp also feed on various types of algae that grow on rocks, coral reefs, and other submerged surfaces. Algae is a crucial food source, providing shrimp with carbohydrates and other nutrients necessary for their growth and health.
4. Small Fish and Invertebrates
Certain shrimp species, especially those in deeper waters, will occasionally consume small fish or other invertebrates. These prey are typically small enough to be captured by the shrimp’s specialized feeding appendages.
5. Bacteria
In some cases, shrimp consume bacteria that proliferate on decaying organic matter or the surfaces of substrates in the ocean. This food source helps shrimp survive in environments where other food options are limited.
6. Decomposing Plant Matter
Shrimp often feed on plant matter that has decomposed and sunk to the ocean floor. This type of food is abundant in coastal areas and provides shrimp with essential fiber and nutrients.
7. Biofilm
Biofilm, a layer of microorganisms such as bacteria and algae that forms on submerged surfaces, is another key food source for shrimp. Ocean shrimp often graze on biofilm, which provides them with a natural, sustainable food source.
Do Shrimp Eat Poop?
While shrimp, such as Amano shrimp, are known for helping to clean up leftover food, waste, and detritus in their environment, they do not directly consume feces. Instead, shrimp primarily feed on decomposing organic matter, such as plant debris and biofilm, which helps maintain ecosystem balance.
In aquariums, shrimp contribute to tank cleanliness and water quality by scavenging uneaten food and breaking down organic waste, which benefits the overall health of the tank. Therefore, when considering what do shrimp eat, it’s important to note that their role as natural cleaners helps prevent the buildup of harmful substances in both the wild and in controlled environments.
Best Shrimp Food for Breeding
To ensure successful breeding and healthy offspring, it’s essential to provide shrimp with the right diet. Below are the best foods to support shrimp during breeding.
1. Protein-rich Foods
High-protein foods, such as brine shrimp, daphnia, and bloodworms, are ideal for promoting reproduction in shrimp. These foods support growth and egg development during the breeding cycle.
2. Algae Wafers
Algae wafers provide essential nutrients, including carbohydrates and minerals, that support shrimp during breeding. They help maintain energy levels and ensure optimal conditions for reproduction.
3. Fresh Vegetables
Fresh vegetables, like spinach and zucchini, offer vitamins, minerals, and fiber to support shrimp health. These vegetables are particularly important for molting, which is crucial for breeding success.
4. Calcium Supplements
Calcium is critical for shrimp during breeding as it aids in shell development and molting. Providing calcium through crushed coral or specialized shrimp foods ensures healthy shell growth.
5. Live Plants
Live plants provide shrimp with a natural food source and help maintain water quality. Shrimp feed on biofilm and algae that grow on these plants, aiding in both their diet and ecosystem health.
6. Biofilm
Biofilm, which forms on tank surfaces, serves as a natural and consistent food source for shrimp during breeding. It helps maintain a healthy, balanced diet while promoting reproductive health.
