so yesterday noticed 1 of my peacock bass sitting at the bottom and breathing rather hard. He didnt come up to feed when I feed them either. So I figured I would change some of my water as it had been a week since i last changed the water. Well I do a 30- 40 % water change and my dumb azz added warmer water by accident. I didnt notice this until I was more than half way back to filling it back up. 
So i quickly switched and re-drained some of the water and refilled with decent temp water. All 7 of my pbass were breathing heavy for a while i was pulling my hair out (if i had any). So after an hour or so I noticed that most were back to normal. Except 2. I figured they would recover but they didn't. They were 2 of the biggest ones I had. 1 i got from bassinmike and the other was a from Connie's. The one from Connie's was the one that was actually taking pellets by themselves. .... I so suck . I want to just kick myself in the nuts. ... the biggest was about 8 inches and the other was about 6 1/2. The others are all fine now and acting normal. hopefully there will be no more mishaps...im so pissed.
