What Do Shrimps Eat?

Shrimp are bottom-dwelling aquatic organisms that contribute significantly to keeping oceans and lakes clean. Being opportunistic omnivores, shrimp will eat anything that fits into their mouths.

Food for shrimps typically includes high levels of animal proteins such as fish flakes or pellets, but you can feed your shrimp more nutritious food by boiling zucchini, spinach or other greens for several minutes prior to giving them.

Shrimp are effective scavengers and bottom crawlers that feed on algae growing on the sides or substrate of tanks, dead plants and leftover bits of fish food floating about in them. Their algae eating capabilities make them particularly useful in tanks with dense vegetation as they eat it while simultaneously keeping the tank clean; easy care instructions allow these shrimp to live up to six years with proper care!

True shrimp are aquatic crustaceans classified under the infraorder Caridea and distinguished by long antennae and legs, an exoskeleton which sheds regularly, lamellar gills and fan-like tails. Found worldwide both fresh and salt water environments, they form an important component of ecosystems; often consumed by larger fish and mollusks, as well as providing humans with protein through human consumption.

Shrimp are popular aquarium inhabitants for their ability to control algae growth while simultaneously adding vibrant color. Beginner and advanced aquarists alike find shrimp an easy choice because they adapt quickly to their environment. However, not all species of shrimp are effective algae eaters; therefore it is necessary to select the appropriate type for your particular aquarium setup.

To choose the appropriate shrimps for your aquarium, the primary considerations should be color and size. Smaller and brightly-colored species tend to be more efficient at eating algae than their darker and larger counterparts, and are also more likely to stay at the surface and less likely to hide in crevices.

Next comes the habitat. It is best to choose an aquarium tank with lots of vegetation so shrimp can thrive more easily while eating algae. Furthermore, regular cleaning of all surfaces in the tank will prevent accumulations of bacteria that cling onto them and spread infection.


Shrimps play an essential role in marine ecosystems as scavengers. By digesting dead fish and sea creatures, shrimps prevent organic waste from building up in marine environments while helping regulate algae and plankton populations – thus making them a common sight in warm and cold waters around the world.

These creatures are opportunistic omnivores that feed on nearly anything they find available to them – including algae, cuttlefish bones, decaying worms (even decaying ones), leaf particles, dead or living plants and even other small shrimps – such as themselves! In essence they’re known as “cockroaches of the sea”.

Home aquarium inhabitants feed off of whatever is growing in their tank as well as any leftover fish flakes or pellets that remain. If you want to add extra protein sources such as frozen brine shrimp, bloodworms or daphnia they’d take that up eagerly as well.

Shrimp are adept at using their legs and tentacles to feel along the seafloor for any prey burrowed into its substrate, an act known as chemosensing that allows them to bridge the gap between sight and smell allowing them to detect chemicals released by potential food sources such as decaying flesh odor.

Shrimp are known to feed on bacteria found in marine environments that form biofilms. These biofilms offer abundant nutrition while the bacteria living inside provide energy sources. When feeding in their natural environments, shrimps often graze for hours on these biofilms that form.

When shrimp spot something they want to eat, they land and grab it with their claws. Keep in mind that shrimp claws have strong bristles on them which makes them ideal for scraping off any unwanted growth on rocks or surfaces in your tank. Furthermore, reddish-brown worms that appear could be harmless detritus worms rather than camallanus or capillaria species of nematode worms which kill certain types of fish.


Shrimps are omnivorous animals, meaning that they eat both plants and animals. As scavengers, shrimp can eat anything they come across such as algae, dead and decaying plants, zooplankton, bacteria, invertebrates such as worms or snails; even other shrimps!

Shrimps are invertebrates, yet possess some distinct features that set them apart from other sea animals. For instance, their legs possess claws with which they use for climbing. Furthermore, their eyes can move independently of each other so they can better see their surroundings. Furthermore, shrimps can move faster than other ocean animals thanks to flexing muscles in their tails to move faster; and can even swim backwards!

As other decapods, shrimps possess a six-segmented abdomen with biramous appendages known as pleopods (PLEE-oh-pods). Lobsters, crayfishes, and shrimps use these appendages to form fanlike tails which snap together for swimming – this feature is known as telsoning.

While most species of shrimp inhabit freshwater environments, a few live in saltwater as well. Examples include Cayman shrimp, coral reef shrimp and tiger shrimp – very adaptable creatures capable of living in nearly any body of water – making them very popular choices for aquariums or other tanks.

People buy shrimp for their colorful appearance and ability to clean out tanks quickly. Furthermore, their care requirements are easy. Unfortunately, not everyone knows that these creatures can also be hazardous; some species such as tiger shrimp can transmit diseases and parasites that could result in serious illness in humans if handled incorrectly.

Pet stores are an excellent resource for purchasing these creatures; just make sure that the species you purchase is genetically pure and healthy. Inquire into their return policy as any quality issues should be easily returned if not satisfied. Also ensure it comes with an identification label which clearly delineates what species it is.


Shrimp are commonly known as the cockroaches of the sea; these marine organisms are opportunistic omnivores that feed on anything they can fit into their mouths, including algae, dead and living plants, worms snails other shrimp and fish as well as bacteria zooplankton and invertebrates.

Shrimp are known to feed on various aquatic lifeforms, from bacteria and zooplankton to algae, invertebrates and even dead fish; as well as being opportunistic feeders who will take advantage of any opportunity that arises to consume anything floating nearby such as dead plant matter or organic debris floating in the water.

Therefore, it is crucial that your shrimp receive an array of foods in their tank in order to receive all the essential vitamins and nutrients they require. You can add fresh or frozen food from time-to-time or use commercial shrimp food high in plant-based nutrients as part of their diet. If you own species of shrimp that require special diet considerations, consult with local fish stores on which brands would best fit them.

When it comes to what plants a shrimp eats, banana, peppermint, mulberry and nettle leaves make an ideal source. Not only do these species aid the shrimp’s health by improving water quality and increasing biodiversity but they can also provide them with security and comfort in their environment.

At times, shrimp may ingest dead fish or shrimp found in their tank. While this behavior may occur occasionally, it should only occur under extreme circumstances and not as part of their regular behavior. It’s best to feed your shrimp a plant-based diet and remove any dead fish/shrimp from your aquarium promptly to prevent ammonia spikes.

Freshwater shrimp may prey upon other members of their own species, but are rarely capable of killing larger saltwater or tropical fish species due to lack of speed, weaponry and digestive capacity.
