Major fish kill when I got back from work today. I added 4 mollies, 1 Pleco, 5 glofish... 1 neon tetra 4 glass neons to my 75 gal that was home to 9 other small fish. Tonight, my 4 glass neon, 1 pleco, 2 angels and 2 loaches are dead. Did a water test, everything was fine. So I did an emergency 50% water change. Praying nothing else dies. What could be the cause?
