Well I came home from school and found my fire shrimp dead on the sand bed. I had him for about a week and all my water parameters are fine. A couple of days ago he was all happy and eating but the last night he hid behind the rocks and this morning he was still there. I have a small pistol shrimp but I don't think he would have killed him because I have seen them fairly close before and the pistol left him alone. My clownfish does like to nip at him, but I don't know why he died. I really want to get another one, but I don't want to kill it. :( can someone please help me, thank you.
