Product Information
Full details
Aquacadabra Artemia Brine Shrimp Cysts are for aquarists needing a reliable, high-protein live food for delicate fish fry and larvae. The key benefit is their consistently high hatch rate, ensuring a readily available food source. A minor consideration is the need for specific conditions (warm, aerated saltwater) to initiate hatching. This product offers a simple way to supplement diets during critical early growth stages in both freshwater and marine environments.

FAQs
What is the best temperature for hatching brine shrimp cysts?
The optimal temperature range for hatching Artemia cysts is between 75°F and 80°F (24°C to 27°C).
How much salt should I use for hatching?
A general guideline is 1 to 2 tablespoons of aquarium salt per liter of water. Ensure it's dissolved completely before adding cysts.
Can I hatch these cysts in freshwater?
No, Artemia cysts require brackish or saltwater conditions to hatch. They are suitable for both freshwater and marine *aquariums* once hatched, but not for hatching in pure freshwater.
How long does it take for the cysts to hatch?
Under optimal conditions, Artemia cysts typically hatch within 24 to 48 hours.
How do I harvest the hatched brine shrimp?
Use a fine-mesh net (specifically designed for brine shrimp) to gently scoop the nauplii from the hatching water. They tend to congregate away from the light, so turning off the light for a few minutes can help gather them.
How should I store unused brine shrimp cysts?
Store unused cysts in a cool, dry place, preferably in an airtight container, away from direct sunlight and moisture to maintain their viability.
Can I feed hatched brine shrimp to adult fish?
While primarily intended for fry and larvae, adult fish may also consume brine shrimp. However, for larger fish, they might be considered more of a treat than a staple diet due to their small size.
Troubleshooting
Low or no hatch rate
Ensure water temperature is within the optimal range (75-80°F / 24-27°C), salinity is correct, and aeration is continuous and sufficient. Check the expiry date of the cysts.
Nauplii do not survive long after hatching
Feed nauplii to fry as soon as possible after hatching. Ensure the hatching water is not contaminated and that the nauplii are harvested and transferred carefully to avoid stress.
Water smells foul during hatching
Increase aeration to ensure sufficient oxygen levels. Remove any uneaten food or debris from the hatching container. Perform a partial water change if necessary, taking care not to disturb the nauplii.
Pros and Cons
Pros
- Consistently high hatch rates ensure reliable food supply.
- Excellent source of protein for optimal fry and larvae development.
- Adaptable for both freshwater and marine aquarium use.
- Quick hatching time of 24-48 hours.
- Simple to hatch with minimal equipment.
Cons
- Requires specific hatching conditions (warm, aerated saltwater).
- Hatched nauplii have a limited lifespan and must be used promptly.
- May require separate setup and hatching process from main aquarium.
Setup, Compatibility & Care
Setup: To hatch the Artemia cysts, you will need a container (like a bottle or small tank), a source of warm water (around 75-80°F or 24-27°C), aquarium salt (approximately 1-2 tablespoons per liter), and an air pump with an airstone to provide aeration. Mix the salt and water, then add the brine shrimp cysts. Ensure continuous aeration and maintain the correct temperature. After 24-48 hours, the nauplii will hatch and can be harvested using a fine-mesh net.
Compatibility: These cysts are suitable for initiating live food cultures for fish fry and larvae in both freshwater and marine aquariums. The hatched brine shrimp are a natural food source for many species.
Care: Store unused cysts in a cool, dry place away from direct sunlight. Once hatched, the brine shrimp nauplii should be fed to your fish promptly as they have a limited lifespan and quickly exhaust their yolk sacs.
