Ever wondered how long those tiny swimming creatures called brine shrimp can actually live? Well, I’ve been raising these fascinating little critters for years, and I’m here to share everything you need to know about their lifespan and how to keep them thriving!
Quick Answer
Brine shrimp typically live for 8-10 weeks under good conditions, though they can survive up to 3-4 months with excellent care. Their eggs can remain viable for 2-3 years when stored properly!
Understanding the Brine Shrimp Life Cycle
Let’s break down their life stages
-
Egg/Cyst Stage
- Remains viable for 2-3 years when stored dry
- Hatches within 24-48 hours in saltwater
-
Larval Stage (Nauplii)
- Lasts 24-48 hours
- Most nutritious stage for fish food
-
Juvenile Stage
- Takes 1-2 weeks
- Rapid growth period
-
Adult Stage
- 2-8 weeks average lifespan
- Can reach up to 12 weeks with perfect care
Factors That Impact Brine Shrimp Lifespan
Water Parameters
-
Temperature: 68-86°F (ideal range)
- Above 90°F = deadly
- Below 60°F = stunted growth
-
Salinity:
- Specific gravity: 1.005-1.080
- Salt concentration: 25-35 ppt
Tank Conditions
-
Space Requirements
- Max density: 300 shrimp per liter
- Overcrowding leads to cannibalism
-
Water Quality
- Regular water changes (10-30% twice weekly)
- Keep ammonia and nitrites low
- Maintain proper pH (7.5-8.5)
Feeding Your Brine Shrimp
To keep your brine shrimp healthy, feed them:
- Microalgae
- Yeast
- Specialized shrimp foods
- Plankton
Pro tip: Feed 2-3 times daily, but don’t overdo it! I learned this the hard way when I once overfed and ended up with cloudy water.
Storage Tips to Extend Lifespan
Here’s what I do to keep my brine shrimp alive longer:
- Harvest using fine net
- Rinse with freshwater
- Store in shallow containers with saltwater
- Refrigerate at 35-40°F
- Use within 2-3 days
Common Problems & Solutions
If your brine shrimp are dying early, check these things:
-
Temperature fluctuations
- Solution: Use a reliable heater
-
Poor water quality
- Solution: More frequent water changes
-
Overcrowding
- Solution: Maintain proper stocking levels
-
Inadequate food
- Solution: Feed varied diet regularly
Fun Facts About Brine Shrimp
Did you know:
- They don’t sleep!
- Females can produce up to 75 eggs daily
- They can’t survive in freshwater
- They can live up to 7 days without food (but please don’t test this!)
Final Thoughts
While brine shrimp might not live as long as other aquarium inhabitants, they’re super interesting creatures that play a vital role in the aquarium hobby. With proper care and attention to their needs, you can maximize their lifespan and enjoy watching these fascinating creatures thrive.
Remember, success with brine shrimp comes down to maintaining stable conditions and regular care. Don’t get discouraged if your first batch doesn’t make it to the full 3-4 months – we’ve all been there! Keep trying and adjusting your care routine until you find what works best in your setup.

How Long Do They Live?
In the wild, a brine shrimps lifespan can vary as it largely depends on environmental conditions. They live on average between two to three months.
Brine shrimp kept as a sea monkey, however, can actually live much longer. As pets, they can live for up to a year. Some have claimed that they have kept their pet sea monkeys alive for five years.
Parsons told Newsweek that he has seen reports recently that they are disappearing in some coastal areas because of human-caused water diversion. Humans disrupt water sources all over the world for a variety of reasons, including pollution, urban growth, and landscape changes. It may be that brine shrimp live longer in captivity because they have a more reliable and consistent saltwater source.
How long can brine shrimp live in a tank?
FAQ
How long can you keep live brine shrimp?
Adult brine shrimp can live in their shipping container for 1 to 2 days. If you are receiving adult brine shrimp, you will need to have water prepared for them. See the Housing section for more information about water chemistry.
What is the life expectancy of brine shrimp?
In the wild, a brine shrimp’s lifespan can vary as it largely depends on environmental conditions. They live on average between two to three months. Brine shrimp kept as a sea monkey, however, can actually live much longer. As pets, they can live for up to a year.
How quickly do brine shrimp grow?
When the water is warm, food is plentiful, and oxygen levels are high, brine shrimp can develop to adulthood in as little as 8 days. The conditions in Great Salt Lake aren’t quite ideal, so it normally takes 3 to 6 weeks for brine shrimp to reach maturity.
How big do brine shrimp get?
Adult brine shrimp typically measure between 0.2 to 0.3 inches in length. Their small size makes them a popular choice for feeding small and juvenile fish species. 10. Can brine shrimp tolerate fluctuations in salinity?
How long does brine shrimp last?
Artemia has a very short lifespan of up to six months. Brine shrimp are very active little creatures that spend their time busily filtering food from the water and breeding. What Fish Make Good Tank Mates For Sea Monkeys? Basically, you can’t keep fish or invertebrates with brine shrimp. There are two reasons for that.
How long can a brine shrimp live without food?
Brine shrimp can survive for up to 7 days without food, provided the water parameters are within the acceptable range. Extended periods without food can weaken their immune system and shorten their lifespan. 8. Can brine shrimp live in a community tank with other fish?
What factors affect the lifespan of brine shrimp?
It is important to maintain the appropriate temperature range to ensure the longevity and well-being of brine shrimp populations. Salinity, the concentration of dissolved salts in water, is another critical environmental factor that significantly impacts the lifespan of brine shrimp.
Can brine shrimp live in water?
Brine shrimp, also known as Artemia, are a species of small aquatic crustaceans that are commonly used as food for aquarium fish and other aquatic pets. These tiny creatures have a unique ability to survive in extreme environmental conditions, such as high salinity and alkaline waters. But how long can brine shrimp actually live?
How long do baby brine shrimp live?
Generally, under optimal conditions, baby brine shrimp can survive for approximately 24 to 36 hours in a well-maintained aquarium environment. However, their longevity can be extended with careful attention to water quality, temperature, and nutrition. The water quality plays a pivotal role in the survival of baby brine shrimp.
