Ever wondered how long those tiny aquatic creatures can survive? Let me break down everything about shrimp lifespan for you – from freshwater pets to saltwater species!
Quick Answer
Most freshwater shrimp live 1-2 years, while saltwater shrimp typically live 2-3 years However, some special species like Supershrimp can live over 20 years, and Harlequin shrimp can survive up to 7 years with proper care
Different Shrimp Species and Their Lifespans
Freshwater Shrimp

Factors Affecting Shrimp Lifespan
1. Water Quality
- No ammonia or nitrite
- Nitrate below 20 ppm
- Well-oxygenated water
- Stable temperature
- Appropriate pH levels
2. Diet Requirements
Our shrimps need a varied diet including
- Biofilm and algae
- High-quality commercial foods
- Fresh vegetables like:
- Spinach
- Zucchini
- Green beans
- Carrots
- Sweet potato
3. Tank Environment
- Live plants for hiding
- Natural decorations
- Appropriate tank mates
- Enough space
- Regular maintenance
6 Pro Tips to Increase Your Shrimp’s Lifespan

Wild vs. Aquarium Shrimp Lifespan
I’ve noticed that wild and aquarium shrimp can have similar lifespans if conditions are right. However, aquarium shrimp often live longer because:
- No natural predators
- Consistent food supply
- Protected environment
- Regular care and monitoring
Common Mistakes That Reduce Shrimp Lifespan
- Skipping water changes
- Overfeeding
- Poor acclimation
- Wrong tank mates
- Sudden parameter changes
- Inadequate hiding places
The lifespan of your shrimp really depends on the species and care you provide. While most freshwater shrimp live 1-2 years and saltwater shrimp 2-3 years, proper care can help them reach their maximum potential lifespan.
Remember, maintaining stable water parameters, providing good nutrition, and creating a natural habitat are key to helping your shrimp live a long, healthy life. And hey, if you’re super lucky and take really good care of them, some species might even surprise you by living way longer than expected!

What do they do?
As I mentioned before, they are janitors. The seas ‘street sweepers,’ so to speak. Not just janitors, though, some shrimp get their fix by being dentists and cleaning the mouth of other fish. The Pacific Cleaner Shrimp species (Lysmata Amboinensis) wave their antennas around in a dancing motion to attract fish and signal to them it’s time to have their check-up. Fish oblige these shrimp and open their mouths, and the shrimp then enter the mouths of these fish and clean off blood-sucking parasites from within.
Something else that may come as a surprise is to know that shrimp are omnivores, meaning they will eat anything. And, if we’re being truthful, they are quite opportunistic. It doesn’t matter whether the thing they eat is alive or dead, they will eat it. It goes to show their level of dedication. Twenty-four hours a day, they are never not doing their job—cleaning up the riffraff. And this is great for ridding the fish tank, the sea, and the streams of minor forms of pollution, like algae, dead and living plants, decaying worms, leftover bits of fish food, etc. I think you get the point.
And just like any good workforce, there are special shrimp dedicated to keeping the sea clean at night. The Peppermint Shrimp species (Lysmata Wurdemanni) are a nocturnal breed. While the other shrimp are scheduling dentist appointments or cleaning up nooks and crannies during the day, these shrimp are taking a good ol’ snooze, resting from a night of hard work.
And when the shrimp get tired of walking everywhere, or perhaps want to take a break from cleaning for a little, they prefer to practice their backstroke. That’s right. Did you know that shrimp are actually really good swimmers? While this isn’t the typical swimming we see from fish (because shrimp have no fins) they can propel themselves backward by flexing their abdominal and tail muscles in quick succession.

Surprising Facts About Shrimp
Have you ever heard the phrase that: “Shrimp are the janitors of the sea?” If you haven’t, don’t be ashamed; we literally just made it up one sentence ago. But it’s true. In today’s blog post, we are breaking down a day in the life of a shrimp, and let me tell you, it is spotless.
Shrimp don’t live very long lives. One to six years is the lifespan of most shrimp. Ghost Shrimp live on the lower end of that range, only up to one year, while Caridean Shrimp can live up to six years. As such, shrimp develop quite quickly, going through several larval stages over just a couple of weeks before they become tiny versions of adult shrimp. This causes the shrimp to consistently molt their skin as they continue to grow. They won’t become full-fledged adult shrimps (and thus be available for consumption) until seven to eight months from the time they hatch.
And while they may not have a long life, it doesn’t make their lives any less important here on the planet. In fact, shrimp play an invaluable role in helping keep our oceans, seas, and streams clean.

It’s the soft parts, like muscles and skin, that tend to elude scientists. So it’s something of a shock that the oldest shrimp on record—from an estimated 360 million years ago—still has its muscles nicely sculpted in stone (above).
