The body count....
Day two or three of having this group of fish we had two days of 99° heat. I lost a FM and a Swordtail. Attributed the deaths to the heat as there was no outward signs of anything else. A few days later in the morning there was two more Swordtails that passed. I tested the water parameters and they were normal 0/0/10.
Another day three more drop dead. Finally the last three each pass away singally. None of them had any outward appearance of anything wrong. No torn up fins from the cichlids or anything like that. There have been no other fish deaths just the Swords and the one FM.
I guess the Swords are just weak genetic wise, no other clue to there demise save the one during the heat. So I am just going to leave things be and monitor to make sure no one else drops dead for no reason before I replace the Swords with either a different type or maybe just get more Tetras and make it a huge group of 40 or maybe another group of 20 Tetras like Bleeding hearts.
