Well i looked into my tank today and i saw my female shrimp's carcass. I am not sure if its moulted skin or her. ill tell you guys a decription to identify. Its in the curled shape like the shrimps you eat. It has its legs all scrunched together like when a spider dies. Its red stripe on her tail is still there. And it looks like there is mass in it (cant see the body that well). She is a full grown 2 inch female.
