My first success in propagating ghost shrimp involved adding a ripe female
to a tank with green water.  She wound up dying after her eggs hatched, but
the nauplii survived, filter-feeding on the green water.  After a few
months, I had a batch of new ghost shrimp.

I've also successfully raised ghost shrimp in an unpopulated 55g tank
plant.  This tank produced high mortality rates because of the filtration
system.  Many of the nauplii would go through the filtration system and not

Ghost shrimp nauplii live as free-swimming little shrimplets in their newly
hatched, 1.5 - 2 mm state.  They float in the current head-down, looking
like slivers of glass in your water.  During this stage, they are filter
feeders.  When they moult, they look like little shrimp and can then both
filter-feed and can feed on food that they collect with their claws.

IMO, the biggest detriment (other than fish in the tank) to raising ghost
shrimp is a filtration system.  Possibly an airlift might be appropriate to
move water, but I wouldn't go farther than that.

I hope this helps,
