To continue on, If you notice on the pic of the sick fish, his pelvic fins also appear to be wounded with raw areas hence my diagnosis of a bacterial infection. My thoughts were that possibly this fish had an internal bacterial infection that worked it's way out or an external infection that probably attacked the brain via the eye. This is why hospital tanks are always a good thing to have available so that at the first sign of trouble, the fish can be medicated then quarantined for a better recovery. In the last import station I worked at, we had almost 1,000 gallons of tankspace dedicated solely to medicating new arrivals because so many fish came in with all sorts of issues that are just natural to wild fish. Medication and QT is mandatory for a healthy main display tank (IMO
Either way, it's always sad to see a fish of this caliber not survive.
I hope this helped
