We are currently only selling nauplii brine shrimp that is freshly hatched. We hatch baby brine Sunday through Tuesday each day to harvest and ship out.  If you want to keep them alive for a few weeks, all you'll need a sponge filter or air bubbler, 5 gallon bucket and live phytoplankton, a powder food, or phytoplankton paste to feed them. 

Brine shrimp grow fast and will reach adults within 2 weeks of arriving. We use Brine Shrimp Direct EZ shell hatch eggs, meaning you won't have to worry about shells in the bottle or about your fish getting shells stuck in their digestive tract.
