Try microfood for shrimp (although you are probably already too late with
this batch). Wager can tell you more about it.

Empires don't need salt to develop, they can do fine in freshwater, although
they are not uncommon in upper estuaries. I doubt they'd tolerate full
salt water, but it would be interesting to know if anyone has tried them
under marine conditions. Same for Pseudomugil signifer, the two often
occur together along the east coast.
