Hey there! Ever wondered what those tiny crustaceans we call shrimp munch on? Well, I’ve done some deep diving into shrimp diets, and let me tell you – plankton is definitely on their menu! Let’s break down everything you need to know about shrimp’s relationship with these microscopic meals
The Quick Answer
Yes, shrimp absolutely eat plankton! In fact, it’s one of their main food sources, especially for baby shrimp. Both types of plankton – phytoplankton (tiny plants) and zooplankton (tiny animals) – are regular items in a shrimp’s diet.
What’s on a Shrimp’s Menu?
Shrimp are pretty much the underwater version of vacuum cleaners – they’ll eat almost anything they can get their tiny claws on! Here’s what’s typically on their menu
- Plankton (both phyto and zoo varieties)
- Algae (string algae, green algae, brown algae)
- Decaying plant matter
- Small mollusks
- Aquatic worms
- Fish waste and leftover food
- Biofilm
- Other tiny crustaceans
How Do Shrimp Hunt Their Microscopic Prey?
You might be wondering – how do these little guys catch something as tiny as plankton? Well, they’ve got some pretty neat tricks up their sleeves (or should I say, shells?):
- Antenna Action: They wave their long antennae through the water to detect plankton
- Special Appendages: Their mouthparts and legs work like tiny nets
- Modified Gills: Act like built-in water filters
- Direct Grazing: Sometimes they just scrape algae and plankton off surfaces
Baby Shrimp and Plankton
Here’s something interesting – baby shrimp (we call them larvae) are SUPER dependent on plankton. It’s basically their primary food source until they grow bigger. Makes sense when you think about it – tiny shrimp need tiny food!
Can Shrimp Live on Just Plankton?
While plankton is awesome for shrimp, they can’t survive on it alone. Here’s why
- Need additional protein sources
- Require calcium from other foods
- Better nutrition from varied diet
- Different nutrients at different life stages
Potential Problems with Plankton
Just like too much of anything isn’t good, same goes for plankton. Here are some things to watch out for:
- Too much phytoplankton can reduce oxygen levels at night
- Large amounts of zooplankton might compete with shrimp for food
- Sudden plankton die-offs can mess with water chemistry
Feeding Time: How Often Do Shrimp Eat?
In the wild, shrimp are opportunistic feeders, which means they’ll eat whenever they find food. But here’s the cool thing – they don’t actually need to eat all the time! These little guys can survive on eating just a few times a week, though wild shrimp typically feed at least once daily.
Tips for Feeding Aquarium Shrimp
If you’re keeping shrimp as pets, here’s what you should know:
- Offer varied diet (not just plankton)
- Include algae wafers
- Add some blanched veggies
- Use quality fish food
- Maintain good water quality
The Bottom Line
So there you have it! Shrimp definitely eat plankton, and it’s a super important part of their diet. But like us humans, they need a balanced diet to stay healthy. These little underwater vacuum cleaners are pretty amazing at adapting to whatever food sources are available to them.
Remember, whether you’re keeping shrimp as pets or just curious about these fascinating creatures, understanding their diet helps us appreciate how they fit into the underwater ecosystem. Pretty neat, right?
Brown Rock Shrimp Diet
Brown Rock Shrimp tend to live shorter lives, between two to three years. But, they more than make up for it by being extremely reproductive during their short life span.
They like to stay near the bottom of the ocean floor snacking on plankton and even other crustaceans. (Shrimp stuffed shrimp, that’s more like it!) As crazy as it sounds, shrimp do on occasion eat fellow shrimps. This happens rarely, and the most common reason is when there is no other food available. Bigger size shrimp will eat smaller shrimp, especially when the smaller ones are weakened or about to die.
Pacific Cleaner Shrimp Diet
Pacific Cleaner Shrimp are some of the most astonishing looking creatures you’ll ever see! These little fellows, who can be identified due to their 10 legs, got their name from their diet. Pacific Cleaner Shrimp tend to eat parasites and dead tissue released from fish. Hard to believe they taste so good when their diet consists of dead fish, but hey, they’re tasty!
They are born males, but become hermaphroditic at the end of their lives.

FAQ
What does plankton get eaten by?
Then the younger fish, plankton-feeding fishes (such as the menhaden and herrings), crustaceans (such as crabs, lobsters, and shrimp), and many other sea animals feed on the plankton. They, in turn, are eaten by larger carnivores such as tuna, halibut, shark, and squid.
What does a shrimp eat in the ocean?
All shrimp are bottom feeders, living as deep as 16,000 feet. This means they sift through the sand and eat everything from algae, plankton, small fish, and other dead organisms.

Do pink shrimp eat phytoplankton?
Pink shrimp larvae feed on plankton (tiny floating plants and animals). Juvenile and adult shrimp are omnivorous, feeding on copepods, small mollusks, diatoms, algae, plant detritus, bacterial films, slime molds, and yeast.
Do shrimp eat plankton?
Moderation is key when feeding plankton to shrimp. Plankton provides an excellent supplementary food source for shrimp. Both phytoplankton and zooplankton deliver vital nutrients that shrimp cannot get from other foods alone. While shrimp eat more than just plankton, it often forms a major part of their diet in the wild.
What do shrimp eat?
It’s important to note that most shrimp species can eat anything, but some have developed special ways to eat. Algae, mollusks, other shrimp, trash, and a wide range of parasitic organisms are common foods for shrimp. Plankton often forms an important part of shrimp diets. But what exactly is plankton, and how do shrimp eat it?
Why do shrimp eat algae and phytoplankton?
They graze on this plant-like substance, scraping it off rocks and surfaces on the ocean floor. Algae is like the bread and butter for shrimp, providing essential nutrients and energy. Phytoplankton is like the “salad course” for shrimp. These microscopic plants float through the water, and shrimp filter them out using specialized mouthparts.
What do pink shrimp eat?
For example, pink shrimp larvae primarily feed on plankton. Juvenile and adult pink shrimp are omnivores that eat a variety of foods including plankton, algae, mollusks, worms, and detritus. Other shrimp like the Gabon shrimp also filter feed on plankton along with algae and insect larvae Cleaner shrimp may pick plankton and parasites off fish
Do shrimp eat plants?
But rather than letting it rot, shrimp consume it, acting like the janitors of the deep. They help recycle nutrients, turning waste into sustenance. It’s all part of their role in maintaining a balanced ecosystem. While plants make up a good portion of their diet, shrimp also enjoy a protein boost from tiny marine creatures.
Do shrimp eat more as they grow?
A shrimp will eat more as it grows. As a small fry, it cannot consume much food at all and a few bits of algae are sufficient. As it grows, it will start to eat a wider range of foods such as plankton and algae and food consumption will gradually increase. Since shrimps are scavengers, they are happy to consume decayed foods.
