i noticed one of my ghost shrimp i just bought has about 30 or so little brown things (all uniform in size and color) in her belly, very close to her "flaps". she keeps moving them and rotating them inside of her. are these eggs?
Of course if you don't catch the babies they will get eaten or sucked in the filter. When it looks like the brown things are about to fall off put her in a hatchery so the babies can fall thru the false bottom to safety. The mommy will eat them also if she can.
