In my time of fish keeping the fish that I have ever had die on me died for 2 reasons.
1. They were already sick when I got them- this is where a quarantine tank comes in handy especially if you have a community tank so it doesn't make the rest of your fish sick.
2. Human error/equipment failure- I've had filters go out on me, some have heaters short circuit and fry their tank(I've never had this problem). Where I killed quite a few fish was in the beginning I had no knowledge whatsoever of cycling a tank. I could have saved a lot of lives if I had known this. That's why it's crucial to read up on cycling and make sure you do it properly so your fish is stress free in their environment.
One thing I forgot to mention and didn't see it mentioned. Test strips are junk! Get yourself an API Liquid Test Kit. It's x1000000000 times more accurate than strips, is a life saver during cycling so you know how far along you are, can give you an idea on your water change schedule, and if you do happen to run into problems you can test your water to make sure nothing is out of whack in the tank
*deep breaths* any other questions feel free to ask
