I bought this shrimp just a few days ago accidentally and she was pregnant. She was fine this morning, but I come home to school and dont see her out like usual. I poked around and looked under a moss ball and found what appeared to be her decapitated? I cant even find the rest of her body or her eggs. Im horrified, i dont know what might have done this. I have another small ghost shrimp in the tank too and hes been fine for weeks. The only things in the tank that pose a threat is my female betta who has never attacked her or my other shrimp. There is also my assassin snails, but i think they would be too small to decapitate her. I dont see any eyes on the corpse and it is too whitish to see if it is hollow. I can see her whiskers too, or where they used to be at least. I will leave this head in the tank for my snails or if she is still alive and wants to eat it. Im praying the lives of her shrimplets were not jeapordized because they looked so healthy.
