Hobby Artemia Hatchery

The Hobby Artemia Hatchery makes hatching live baby brine shrimp almost effortless, with no air pump and no siphoning. It is a shallow ring-shaped dish: you fill the outer ring with salt water and brine shrimp eggs and snap on the black lid. As the nauplii hatch they swim toward the light entering through the opening in the center and gather in the clear central well, leaving the empty shells behind in the dark outer ring. Scoop them out with the included sieve spoon and feed. Made in Germany by Hobby, it is the tidiest way to keep fry, seahorses, and picky fish supplied with live food. Pair it with Bulk Reef Supply Brine Shrimp Eggs or SFBB Hatch Mix, and browse all of our fish foods.

Why You'll Love It

• No air pump, no mess. Passive hatching with nothing to plug in and no bottle to rig up.
• Self-separating. Light draws the hatched nauplii into the center well away from the shells, so harvesting is clean.
• Compact. Sits on a shelf or windowsill; needs only room-temperature light.
• Reusable for years. Sturdy plastic dish and lid; rinse and refill for the next batch.

How to Use

Fill the outer ring with salt water (about 1 tablespoon of salt per liter), sprinkle in a small amount of brine shrimp eggs, and fit the lid. Place it where light reaches the center opening, at roughly 75 to 82 F. In 24 to 48 hours the nauplii collect in the central well. Lift them out with the sieve spoon, rinse briefly in fresh water, and feed. Empty, rinse, and restart for a continuous supply.

Frequently Asked Questions

Do I need an air pump or heater? No. The dish hatches passively at room temperature; warmer rooms hatch faster.

How do the shrimp separate from the shells? Nauplii swim toward light. The lid keeps the outer ring dark and the center bright, so they migrate into the collection well on their own.

Are eggs included? No, buy the eggs separately; any brine shrimp cysts work.
