Why Hobbyists Choose Aquarium Co-Op Eggs
- High hatch rate:premium-grade cysts deliver dense, healthy nauplii.
- Universal first food:perfect for fry of bettas, killifish, cichlids, livebearers, tetras, angelfish, discus, gouramis, and saltwater clownfish.
- Brine-rich nutrition:newly hatched nauplii are loaded with yolk-sac lipids and amino acids.
- Triggers picky eaters:the swimming motion entices wild-caught and finicky fish that snub dry food.
- Sealed for freshness:resealable container keeps eggs viable in the fridge for months.
Hatching Guide
- Mix saltwater:dissolve 1–2 tablespoons of non-iodized aquarium salt per quart of dechlorinated water in a clean 2-liter bottle or hatchery jar.
- Add eggs:sprinkle ¼–½ teaspoon of eggs into the water.
- Aerate:drop an airstone or open airline to the bottom and run a constant, vigorous stream of bubbles for 24–36 hours.
- Maintain temp:hold the water between 78–82°F for fastest, most reliable hatching.
- Harvest:shut off the air, let the hatch settle 5–10 minutes, empty shells float, unhatched eggs sink, and the bright orange nauplii gather near the bottom or toward a light source.
- Rinse & feed:siphon the nauplii through a fine brine shrimp net, rinse briefly with fresh water, and feed to fry 1–2 times daily.
Tip:always rinse harvested nauplii before adding to freshwater tanks to avoid raising salinity, especially in fry-raising tanks.

FAQ
Do I need a special hatchery?
No, a clean 2-liter bottle, an airline with no airstone (or a coarse one), and aquarium salt will do the job. A purpose-built hatchery just makes the process cleaner and easier to harvest.
How long do unhatched eggs last?
Stored sealed in the fridge, hatch rate stays strong for 6–12 months. Keep them dry and away from humidity for best results.
Can I feed baby brine to adult fish?
Absolutely. Adult killifish, small tetras, bettas, gouramis, and clownfish love live nauplii as a conditioning food before breeding. Larger fish do better with adult brine shrimp.
Freshwater or saltwater?
The eggs hatch in salt water, but rinsed nauplii can be fed to any freshwater or saltwater fish. Always rinse before adding to a freshwater tank.
