Added a flame angel and a fair wrasse. They were in there 2 weeks before the deaths started.Anything new added to the tank that could have brought in some nasties? I like to shorten my lights if there is stress in a tank. So sorry

Trying to think, but i highly doubt it. Im consistent with what i add and do not add to the tank,If the fish were in the new tank for over a month and you made no other changes, then I highly doubt it was lack of oxygen. Is it possible something got into the tank from outside, like a chemical of some sort?
When i clean the outside glass, i spray ammonia free windex onto the napkin. Got a glass tank lid and the tank is enclosed inside a stand with a canopy.
