Ammano shrimp?
Copied from a web site.
The Amano Shrimp is one of the more difficult shrimp to successfully breed in the home aquarium. The young shrimp do not hatch as small versions of the adults, like a Red Cherry Shrimp does, but they hatch as larva. These larva require salt water to grow to metamorphosis and become freshwater shrimp again. The easiest way to determine the sex of an Amano Shrimp is their lowest stripe along the length of the body. Male shrimp have a line of separate dots while females have dashes almost appearing to be a broken line.
