Also, with a reading of .25ppm nitrates, your water parameters seem fine. Water quality isn't the issue.
I kind of disagree with the .25ppm. Everything I've read says that they are horrible with any trates in the water. Even minute amounts can hurt these guys.
With that said, I do not believe that was the cause of death, neither do I believe it is aggression. I'd be willing to bet there is some sort of contaminate in the water. Maybe some sort of oil as it floats and would hurt the fish, but may take longer to get to the inverts.
