I purchased a smal sixline wrasse yesterday. In my previous tank I had great success with them, generally very easy to keep fish. In the LFS he looked healthy, ate like a pig. Everything seemed to be fine when I got home, wake up and hermits have his dead body tackled in the back of the tank. Any ideas on what happened? No signs of disease or bad health, is it possible the hermits ganged up on him? I've NEVER had this happen was kinda baffled
