I came home and saw all my fish gasping and breathing hard last night. I instantly checked my parameters and everything seemed fine. Salinity was slightly high at 1.028. When I woke up 4/5 had died. 2 clowns, 1 bicolor blenny and a 6line. My Watchman Goby was fine. All my corals seemed fine. The anemone was a bit shriveled but the next day opened up as usual. I have no idea what happened. I took the water to the LFS and they said everything was good as well. I haven't done anything different outside of water changes. It's a 32.5 Fluval. Any ideas of what could've happened?
Also my peppermint shrimps, snails and hermits are all fine.
