Any fishkeepers here? Saltwater or freshwater

Of course it's just a guess, but I would guess the eye symptoms were a secondary bacterial infection. Aeromonas is a pretty opportunistic bacteria so it's possible the eye was infected because the fish's health was degraded in general. I guess it's also possible that Aeromonas was the primary culprit, since it can result in pretty severe tissue loss if unchecked. However, again it would be extremely rare for it to be bad enough to "rot out" a fish like that before you ever noticed any surface lesions.

Very, very true. We had a situation similar to yours, where we had 14 ghost shrimp all die overnight. Never did figure out why. Luckily they're only .33 each!
