Just noticed today.
I have a 90-gallon fully-stocked authentic Lake Malawi tank with a mixture of carefully-selected peacocks, haps, and mbuna. They all get along fine, except with this recent heat-wave the water temperature has reached 88 degrees and they've become quite aggressive. My smallest Red Zebra was picked to death, my first fish death since getting this tank a year ago. Very unlike the other fish to do such a thing.
Then today I find one of my fish has a white eye. I forget the name of it but it's a 1st generation sub-adult hap.
The water conditions are fine other than temp.
What could it be? Here's a photo...
