It can happen in a matter of hrs. A swing in your tanks chemistry could cause 1 soft coral to die then the toxis released can cause your other corals to start to go, soft corals can release way worse stuff then hard corals. Tanks getting nuked doesn't happen over a long period it can be overnight. And the first thing everyone is going to ask you for when you come calling help is exactly what all your water parameters are.I know corals release much more toxins and things but if I remove it right away and do a water change won’t it be fine?
