I found my Peppermint shrimp dead in a tight spot betwwen two rocks today. I cant find any reason for why it would have died. all my water levels are great except for nitrates, which are at 10. he was usually pretty active and crawled around alot on the rocks and sand, until i got my stronger lighting a couple days ago. he stopped moving around so much and hid most of the day. i thought he was just a little scared because of the brighter lights, but then he died. could he have died from stress of the lights?
