As far as i can work out. The shrimp needs to be moved to a seperate tank until larvae have hatch then remove. They then need to be moved to sea water no later than 8 days after hatching the salinity of the water has to be with 5ppt. They then stay in that water until post they metamorph to miniture shrimp. Then dilute the salt down to specific salinity. They are are fine to go into fresh water. I have read plenty about it but it would be nice to talk to some one first hand as i go through the process.
