You need to provide more information to be able to provide any insights into what has happened. You have other fish in the tank. How long have you had them? Have you added any new fish recently? Did you quarantine them before adding? Did you do anything to the tank right before they died? How is the stress level in the tank? How long were the fish dead in your tank before you removed them? Did you remove them? Did you find them? If you didn't find them did you check behind the tank on the floor for bodies? What about in the overflow? Were the fish eating before they died? Did you check your ammonia levels before the fish died?
You have a over 150 gallons of water in the tank why is your ammonia levels even rising when your fish died?
Are the other fish showing any signs? Are they eating?
Sometimes fish just die? When we buy them we do not know their ages.
