bought some test shirmp for a new tank from my LFS labeled 'ghost shirmp,' but i'm having second thoughts. they don't have those orange markings that are often associated with ghost shrimp.
you wont have to worry about babies. judging by the berried shrimp they are a low order breeder and the babies will be larva and need salt water to breed. they probably wont make it in fresh water.
Most ghost shrimp require some salinity to hatch and then they go through a larval stage and if nothing eats them they'll need access to a lot of infusoria... I wouldn't worry about it
