Why does "IT" always happen at night

[my2rotties]

Why do fish get sick, die, jump out and anything that can go wrong happen while we sleep? I've been fairly lucky with this system but my last one was awful. I would get up in the morning to tanks crashes, sick r dying fish r equipment failure. With this system my jumpers always did while I slept, or my Majectic angel fell ill and I found her in the morning. Then the day after that she was dead when I woke up but looked promising when I went to bed.

SO why does bad stuff always seem to happen while we sleep. I am awake much longer during the day so what is it abut the slumbering hours?
