Ammonia was none or really really low. No slime or white dots. She ate this morning and I didn't notice anything until after I added some live rock. I checked all my levels after I added the live rock and everything was good. Nitrates were less than 5. The only thing that was a little low was the pH but the chart said it was still good. I just went to check on her and she was dead. I really want to know how she died. The lady at my LFS
said it was probably stress from adding the live rock. She is very knowledgeable about saltwater tanks so I believe her.
