I currently have about 20 or so small cherry red shrimp in a planted 6 gallon tank. I havent seen any corpses, but I occasionally find empty shells. They tend to be the bigger of the shrimp, from the shells. Does anyone know if they are molting, or are they eating each other? I think they are molting, but dont have any experience with shrimp, so it's all new to me. Any help is appreciated.
