Hey there! I’ve spent countless hours studying these fascinating little creatures, and I’m excited to share everything I know about grass shrimp and their eating habits. Let’s dive into their world!
The Basic Diet of Grass Shrimp
Grass shrimp aren’t picky eaters! These tiny crustaceans love to munch on:
- Worms (their favorite snack!)
- Algae (both floating and attached to surfaces)
- Tiny crustaceans (yeah, they eat their smaller cousins)
- Detritus (dead plant and animal matter)
- Microorganisms
How Do Grass Shrimp Feed?
These little guys are pretty smart when it comes to finding food! Here’s what I’ve observed
- They use their first two pairs of legs (which have tiny claws) to grab food
- They’re most active during dawn and dusk
- They forage in shallow waters, especially around:
- Bay grass beds
- Marsh areas
- Sandy bottoms
- Rocky areas
Where Can You Find Grass Shrimp?
These transparent little fellows are everywhere in the Chesapeake Bay area! You’ll typically spot them
- In shallow waters (their favorite hangout)
- Among bay grass beds
- In tidal rivers
- Moving to deeper, warmer waters during winter
Cool Facts About Grass Shrimp
Did ya know? Here are some interesting tidbits about these creatures:
- They grow up to 1.5 inches long
- Their bodies are almost see-through!
- They got this cool “horn” thing over their eyes
- They only live for about a year
- They’re super important for the ecosystem
The Circle of Life: Predators and Survival
While grass shrimp are busy eating their favorite foods they’re also on someone else’s menu! Their main predators are
- Sunfish
- Killifish
- Other small fish
Why Grass Shrimp Matter
These little guys are more important than you might think! They:
- Help clean up dead plant and animal matter
- Serve as food for larger fish
- Act as indicators of water quality
- Keep algae populations in check
Seasonal Changes in Diet
Their eating habits change throughout the year:
| Season | Primary Food Sources |
|---|---|
| Spring | Fresh algae growth, tiny crustaceans |
| Summer | Varied diet, most active feeding |
| Fall | Detritus, remaining algae |
| Winter | Less active, opportunistic feeding |
Tips for Observing Grass Shrimp
Wanna see these cool creatures in action? Here’s what I recommend:
- Look in shallow water during early morning or evening
- Use a small net near grass beds
- Check around dock pilings
- Look for their transparent bodies – they’re like little ghosts in the water!
Conservation and Environmental Impact
We gotta keep these little guys around! They’re super important for:
- Water quality monitoring
- Fish population health
- Ecosystem balance
- Scientific research
Interesting Behaviors
When it comes to eating, grass shrimp show some pretty cool behaviors:
- They’re most active at dawn and dusk
- They use their antennae to sense food
- They can swim backwards to escape danger
- They sometimes gather in large groups while feeding
Health and Population Concerns
The good news is that grass shrimp populations are generally stable! But they face some challenges:
- Water pollution
- Habitat loss
- Climate change
- Human development
Final Thoughts
After spending so much time studying these fascinating creatures, I can tell you they’re way more interesting than they first appear! Their eating habits and behaviors make them super important for our waterways.
Remember, these tiny transparent shrimp are doing a big job in our ecosystems. Whether they’re munching on algae or becoming a snack for larger fish, they’re a crucial part of the food web.

Setting up a ghost shrimp aquarium
One of the reasons ghost shrimp are one of the most popular invertebrate species in the aquarium hobby is because theyre so easy to keep alive. They dont require a specialized aquarium set-up and a tank of at least 10 gallons (38L) should be large enough to sustain a colony. You can keep around three ghost shrimp per gallon without any issues.
As always, your aquarium should be filtered and fully cycled before any shrimp are added. Although ghost shrimp can handle a relatively wide temperature range, its usually a good idea to always use a heater to prevent sudden temperature fluctuations.
Like all shrimp, this species can become skittish if the aquarium lacks hiding places. Palaemonetes shrimp love a heavily planted tank! If you want to see your shrimps natural (foraging) behavior be sure to use plenty of live plants, hides like shrimp tubes and flats, driftwood, and natural rocks.
Palaemonetes shrimp are popular as feeder shrimp because theyre known to be hardy and can handle bad water quality fairly well. This makes it easy to ship and house them in massive amounts; after all, if a few die, its not like a lot of money is lost.
Obviously, things are a little different if you keep these shrimp in your display aquarium. If you want them to live a long and happy life, its important to keep the water quality high. That means the tank should always be fully cycled (zero ammonia, zero nitrite and nitrates as low as possible).
Overstocking is not much of a worry if you only keep ghost shrimp, as their bioload is very low, but its something to keep in mind if youre going for a community tank. Room temperature is fine, but as discussed above its a good idea to still use a heater as backup.
pH: 7.0-7.8
Temperature: 65-82 °F/18-27.5 °C
Water hardness: 3-15 dkh
Because they are a little larger than dwarf shrimp, there is less risk of your Palaemonetes shrimp being eaten by their tankmates. That being said, you should still avoid keeping them with any fish that might have an appetite for shrimp! Peaceful tankmates are a must for any shrimp. If youre interested in actively breeding your ghost shrimp, you might want to consider setting up a single-species tank, as the larvae are very vulnerable.
Keep in mind that ghost shrimp are known to be slightly more aggressive than dwarf shrimp. Fish with long fins, such as Bettas, might be damaged by these opportunistic feeders.
Ghost shrimp appearance & natural habitat
The name “ghost shrimp” can be a little confusing, as its commonly applied to various translucent freshwater shrimp. True ghost shrimp belong to the genus Palaemonetes, of which Palaemonetes paludosus (also called grass shrimp or glass shrimp) is most commonly found in the aquarium trade.
Whisker shrimp in particular, and Amano shrimp to a lesser degree, may be mislabeled as ghost shrimp in aquarium stores. The latter is not a problem, as Amanos are peaceful and efficient algae eaters. The former can be an issue, because whisker shrimp are larger and more aggressive than ghosts. Make sure youre buying the right shrimp!
A true ghost shrimp grows to around 2″ in length. It has a translucent body with fine speckling and a significant back hump. Look for orange bands around the antennae and front claws: if those are present, its definitely Palaemonetes paludosus.
Did you know that the ghost shrimp is naturally found in North America? Its perfect for a USA native species-centered aquarium! Palaemonetes paludosus calls the eastern part of the country home, from Massachusetts to Wisconsin in the north and Florida to eastern Texas in the south.
Ghost shrimp arent very picky about habitat. Their only real requirement is for plenty of aquatic vegetation to be present, as this helps them hide from predators. The shrimp can be found in lakes, ponds, streams, and similar—theyve even popped up in brackish areas. However, this likely mostly happens by accident, as ghost shrimp are decidedly a freshwater species.
The IUCN Red List considers Palaemonetes paludosus to be a species of Least Concern, meaning its not threatened in the wild. The population appears to be stable; ghost shrimp are actually an introduced species in parts of the country. In fact, the government introduced it in the lower Colorado River itself.

FAQ
What can you feed grass shrimp?
In the wild, shrimp feed primarily on algae, decaying plant matter, and biofilm. Captive shrimp will continue to eat these foods but will also accept algae wafers, shrimp pellets, and other commercial foods.
What do common grass shrimp eat?
Grass shrimp feed on detritus, algae, and dead plant and animal material. In turn, grass shrimp are consumed in large quantities by commercially important fishes and forage species such as spotted seatrout, red drum, and mummichogs.
What is the lifespan of grass shrimp?
The lifespan of a grass shrimp is typically around one year. They hatch from eggs into larvae, go through several developmental stages, and then mature into adults, usually living for about 6 to 13 months.
