I've had my peppermint and coral banded for months in my 28g nano cube. They were doing fine until 2 days ago I saw pepper remains, and the next day my CBSs lifeless body...definitely not molts. My questions is could this have been caused by moving LR?? I did a normal water change (RO/DI water with same salinity and 0 TDS) and moved the LR around in a way which I hadn't before, since Im fighting this horrible hair algae attack. After what felt like years of pullign hair from the LR, I put them back in normal order, no shrimps crushed. But the day this and the water change after the deaths started. I find this too odd to be a coincidence, and worry, although all my coral,snails, my ocellaris, and my goby appear fine.
