I purchased a Coral Beauty from the LFS and she seemed great and healthy. I put her in my tank with two small clowns, 1.5" each, a few snails and a cleaner shrimp. She hid for about 4 days, then started coming out. She looked great and healthy. Last night, about 8 days later she is dead. I looked over her body, and she still looked perfect. I checked my water 0 Ammonia, 0 Nitrites, 20PPM Nitrate PH 8.2 Sal: 1.023. Now I am a little worried to purchase another fish for my tank in fear that it will happen again, since she wasn't s really cheap fish.
