I have several ghost shrimp in my aquarium at my apartment. they are so cool to watch since you can see right through them. I have lots of greenery for them to hide in so that my big fish doesn't pick on them.
It's not recommended for expectant mothers to eat shrimp regardless how it is cooked or prepared. Some methods tend to be less dangerous than others, but if you do eat shrimp during pregnancy there'll always be some associated risk. http://pregdiets.com/can-you-eat-shrimp-while-pregnant.html pet shrimp
