So frustrating. Everyone else is fine.

Unless you find your missing fish the problem is likely a lack of oxygen event that caused some of your fish to die.
Alternatively, you can be experiencing a cycle. You should check your parameters.
Alternatively, you may have had a temperature spike.

It is doubtful that anything in your tank attacked, killed and ate two fish and killed and partially ate the other in one evening.
