The fatheads didn’t worry me cause it was a week the top of the ice melted, hundreds of them swam on the surface and then it froze again.. so yeah they were doomed. As for a rapid change that might make the most sense. I turned the deep end aeration on during the 40-50 degree days but maybe it was just too much for them.
But otherwise this is shouldn’t be a yearly thing? Definitely “my fault” kinda deal?
Hopefully those are all that come up but I just found another perch last night
