Adding so many fish all at one time can make the ammonia spike, and this is very hard on the fish, can easily kill them. If the ammonia test is anything but zero, then this is part of the problem. The tank is large enough, that if the fish were quite young, small, this may not cause an ammonia spike.

When you added the fish to the tank, how did you do it? Let the bag hang in the tank to equalize the temperature? Slowly mix tank water into the bag to make a more gradual adjustment to water chemistry? Drip acclimate?
