I can't tell you what happened, but do you have a quarantine tank that you can put the survivors in? Or even a bucket with pretreated water and maybe an air stone?

How often do you change your water?

This is hard to tell without knowing some history. Your parameters could have been fine last week but your pH could have dropped, temperature variations, lack of water changes, overfeeding, filter issue raising your ammonia etc

Your filter may have stopped. I know if you don't clean it out every month or so it can build up and be released.
