Ok, that will answer why your fish died.
When fish waste decomposes in the water it creates ammonia, which is toxic to fish. There is a naturally occurring bacteria that breaks it down into nitrite, which is even more toxic to fish. Another bacteria breaks the nitrite down into nitrate, which isn't so toxic fish. While the bacteria is present naturally, it takes some time for it to build up to the level it needs to be at to keep ammo and nitrite from lethal levels in an aquarium.
Since you have fish in your aquarium already, it's important to to add a product like Tetra SafeStart. I've also had good look with Seachem Stability. Both contain the bacteria you need in the tank, which will help shorten the cycle.
Plants help alot, because they "eat" nitrogen (ammo, nitrite, nitrate). You can try to see if Janelle will give you some hornwort; it's a nitrogen hog. Just float it on top of the tank and it should keep the levels down a little bit. But you still need to add SafeStart or Stability. Several people on here know other products that work, but most products that boast they add beneficial bacteria don't work well.
The definition of insanity is doing the same thing over and over again and expecting different results.
