When raising fry, shrimp, nano fish and other small aquatic animals, brine shrimp is one of the most popular high-protein foods available.
But there are two convenient ways to feed it:
Freshly Hatched Baby Brine Shrimp (BBS)
vs
Decapsulated Brine Shrimp Eggs
Both can be excellent foods, but they are used differently. Here’s how to decide which one is right for your aquarium.
🦐 What Are Baby Brine Shrimp (BBS)?
Baby Brine Shrimp are freshly hatched Artemia nauplii.
To produce BBS, Artemia cysts are placed in saltwater with strong aeration and suitable temperature and lighting. Once the eggs hatch, the baby brine shrimp are collected, rinsed and fed to your fish.
The biggest advantage is simple: they’re alive and moving.
That movement naturally triggers the hunting and feeding response of many fish, making freshly hatched BBS particularly useful for fry and picky eaters.
Why Aquarists Love BBS
✓ Live, moving food
✓ Excellent for growing fish fry
✓ Encourages natural hunting behaviour
✓ Great for many nano fish
✓ Useful for conditioning breeding fish
✓ Easy to produce regularly once you have a hatchery running
Freshly hatched BBS are especially popular for species such as Corydoras fry, guppies, bettas, rainbowfish, Apistogramma and many other small fish.
🥚 What Are Decapsulated Brine Shrimp Eggs?
Decapsulated brine shrimp eggs are Artemia cysts that have had their hard outer shell removed.
Unlike normal Artemia cysts, they can be used as a ready-to-feed food without having to hatch them first.
This makes them incredibly convenient.
Simply take the required amount, soak them in aquarium water for around 10–15 minutes, and feed a small amount.
Why Use Decapsulated Eggs?
✓ No hatchery required
✓ No saltwater preparation
✓ No air pump or harvesting
✓ Very easy to store
✓ Excellent for small fish and fry
✓ Convenient high-protein food
✓ No hard outer cyst shell being fed to the aquarium
✓ Great backup when you don’t have live BBS available
For breeders running multiple tanks, decapsulated eggs can save a considerable amount of time.

🐟 Which One Should You Choose?
If you want the benefits of live food and maximum feeding response, freshly hatched Baby Brine Shrimp are difficult to beat.
Their constant movement encourages fry to hunt and eat, which is particularly useful with species that don’t immediately recognise prepared foods.
If you want something quick, simple and convenient, decapsulated brine shrimp eggs are an excellent alternative.
There’s no hatchery to maintain and no need to wait for eggs to hatch.
Our Favourite Approach: Use Both
You don’t necessarily have to choose one.
Many breeders can benefit from keeping both Artemia cysts and decapsulated eggs available.
Feed freshly hatched BBS when possible, while keeping decapsulated eggs available for days when you don’t have a fresh hatch ready.
It gives you the benefits of live food without being completely dependent on your BBS hatchery.
🦐 Can Shrimp Eat Decapsulated Brine Shrimp Eggs?
Yes. Decapsulated brine shrimp eggs can also be offered to freshwater shrimp as a protein-rich supplementary food.
Because the particles are very small, they can be useful in shrimp tanks containing juveniles.
As with any concentrated food, feed sparingly. Excess food should not be allowed to accumulate in the aquarium.
⚠️ Don’t Feed Normal Unhatched Artemia Cysts
There is an important difference between regular Artemia cysts and decapsulated Artemia eggs.
Regular cysts still have their hard outer shell and are primarily intended for hatching.
Decapsulated eggs have had this outer shell removed and are specifically suitable for direct feeding.
So if you want to feed the eggs directly, make sure you’re using decapsulated brine shrimp eggs, not ordinary Artemia cysts.

Final Verdict
Choose freshly hatched BBS if: you want live movement, strong feeding response and an excellent live food for growing fry.
Choose decapsulated eggs if: you want convenience, easy storage and a nutritious food without having to hatch Artemia every day.
For breeders? Keep both.
Fresh BBS can be your primary live food, while decapsulated eggs make an extremely convenient backup.
