Hey fish keepers! I’ve been raising brine shrimp for my aquarium fish for over 5 years now, and lemme tell you – it’s way easier than you might think! Today I’m gonna share everything I’ve learned about growing these little swimming snacks from eggs all the way to adults. Trust me, your fish will thank you for the effort!
Why Should You Grow Your Own Adult Brine Shrimp?
Before we dive in (pun intended!) here’s why raising brine shrimp to adulthood is totally worth it
- Adult brine shrimp are WAY more nutritious than baby ones
- They’re bigger (400-500 microns) – perfect for larger fish
- They’ll actually reproduce in your tank = endless food supply
- Adults can live for weeks (babies only last 2-3 days)
- It’s cheaper than constantly buying them
- They’re super adaptable to different conditions
What You’ll Need to Get Started
Here’s your shopping list:
- 5-10 gallon tank or plastic container
- Air pump + airline tubing
- Air stones or bubblers
- Aquarium heater
- Tank lid (trust me, these guys can jump!)
- Marine salt (not table salt!)
- Hydrometer for measuring salinity
- Brine shrimp food
Step-by-Step Guide to Raising Adult Brine Shrimp
1. Setting Up Your Grow-out Tank
First things first – let’s get that tank ready:
- Fill your container with dechlorinated water
- Add marine salt until you reach 1.010-1.018 specific gravity
- Install your air pump and stones
- Set heater to 82-86°F
- Add bright lighting (helps grow natural food)
2. Adding Your Baby Brine Shrimp
Once your tank’s ready
- Rinse newly hatched nauplii with clean saltwater
- Add about 1 teaspoon of babies per gallon
- Make sure aeration is running well
- Keep water moving constantly
3. Feeding Your Growing Shrimp
These little guys need constant food to grow big and strong! Here’s what I feed mine
- Liquid fry food
- Powdered spirulina
- Yeast-based shrimp foods
- Phytoplankton
- Micro pellets
Pro tip: Feed 2-3 times daily, but don’t overdo it! Too much food = messy tank.
4. Maintaining Your Brine Shrimp Colony
Weekly maintenance is super important:
- Change 15-25% water weekly
- Use pre-mixed saltwater at same temp
- Vacuum bottom gently
- Test water parameters regularly
- Remove uneaten food
5. Harvesting Your Adult Brine Shrimp
After 2-4 weeks, your shrimp should be adult-sized (about 1/2 inch). Here’s how to harvest:
- Use a fine mesh net
- Scoop out what you need
- Rinse in tank water
- Feed to your happy fish!
Leave some adults in there to keep breeding – they’ll maintain the population themselves.
Common Problems & Solutions
We all mess up sometimes! Here’s how to fix common issues:
- Cloudy water? You’re probably overfeeding
- Dying shrimp? Check your salinity and temp
- Slow growth? Try varying their diet
- Lethargic shrimp? Increase aeration
Tips for Success
After years of trial and error, here’s what I’ve learned:
- Start small – don’t add too many babies at once
- Keep water moving constantly
- Monitor water quality weekly
- Mix up their food sources
- Be patient – it takes 18-21 days to reach adulthood
Final Thoughts
Growing brine shrimp to adults isn’t rocket science, but it does need some attention and care. Once you get the hang of it tho, you’ll have an endless supply of nutritious live food for your fish!
Remember: healthy brine shrimp = healthy fish. And there’s nothing better than watching your fish go crazy for food you grew yourself!

Happy shrimp raising!
Note: This guide is based on my personal experience and research. Your results might vary depending on your specific setup and conditions.
Feeding Brine Shrimp
- 1 Use enrichment formulas. Selcon is a popular brand, and there are many others available at most aquarium stores. Ask an employee for help if you have trouble finding the formulas, or use an online store to buy the food in bulk.
- 2 Feed the brine shrimp yeast, pureed greens, powdered eggs, or powdered milk. Brine shrimp are not picky, and they will eat these human foods. Spirulina is another option to feed the brine shrimp.
- 3 Feed only small amounts, but do so several times a day. Do not overfeed the brine shrimp! If the tank water begins to look excessively murky and dirty with food, clean the tank and feed the brine shrimp smaller amounts.

Hatching Brine Shrimp
- 1 Buy brine shrimp eggs. Packets of dehydrated brine shrimp cysts are sold at aquarium and pet stores.[4] Beginning with one packet is fine, since the brine shrimp will multiply rapidly.
- 2 Place the cysts in the water, and they will hatch after 15 to 20 hours.[5] If your tank is the correct temperature and salinity for the shrimp, they will hatch within a day. 12 hours after that, you will have young shrimp swimming around in the tank.
- 3 Enjoy watching the brine shrimp population grow. Brine shrimp will multiply quickly. They will begin as tiny cysts and end up as small shrimp. You do not need to aid them in hatching or growing, since they will do so naturally in a well-maintained tank.
- If your brine shrimp are not growing or hatching, check the salinity and temperature of the tank for problems.
- It is natural for some of the brine shrimp to die.
