I work form home, so have the advantage of scanning my tank often.
Yesterday, around 5pm I check my tank and all is well, all fish are happy.
1 hour later one of my regal tangs is on it's side, nose under a rock with body on the sand.
As these tangs tend to "sleep" a lot, I suspect it's asleep.
Just before dinner time (around 7:30pm) it's dead.
All other fish are unaffected. Dead fish shows no sign of trauma or sickness.
Question. Do fish die of heart failure/stokes?
