my Amano and Ghost shrimp are always preggers. They are quite a bit larger then the males. Amano shrimp seem to carry more eggs. After about two weeks you can see little black dots on the eggs (eyes). Brackish water is needed to successfully keep the baby shrimp going. I haven't be able to successfully hatch any babies yet. I have to do more research about brackish water.
So a guy walks into a Pet Store
Guy: "I have Algae on my drift wood!"
Pet Clerk: "Take two Plecos and call me next week."
