NT Artemia revolution: Decapsulated brine shrimp eggs (Brine shrimp eggs without shells) For growing on to adult or for feeding, newly hatched, direct to fry or invertebrates. The eggs are preserved virtually indefinitely in a special fluid. Each hatch will provide around 10,000 brine shrimp. Add 3-5 drops per hatcher and leave in the aquarium under light for 24 hours. Then strain the shrimps under a fine mesh shrimp net, or coffee filter paper and feed them to your fish.
