What could be killing my fish? I tested my water twice and everythings good. They told me to check my temp. If not that what else can it be

Maybe your salinity is low.

I know you tested your water and its was good but I suggest you post your parameters...and some tank info..

whats in your tank? what died? how old is your tank? what is your temp, salinity, nitrates, nitrites, amonia, ect?

if you want help you have to be way more specific on whats going on...
