Need some help trying to figure out what this is and how it happened. Is there anything I can do for the fish? I just noticed the bulging eye today. I don't have a QT setup but separated the fish into a acclimation box.
Any thoughts?

Thank you for the information. Unfortunately the fish didn't make it through the night. I do have a Flame Angel that has been super aggressive chasing other fish so it's quite possible it was a trauma and stress issue. Might need to find a new home for him soon.If just the one eye is affected, this is most likely from a mechanical injury - the fish gets frightened, hits a tank wall or something and the eye swells up. Assuming no other issues, and the fish still eats o.k., this can get better in a few weeks. Sometimes, secondary bacterial infections start in, and then you should treat with erythromycin (Maracyn 1) in a treatment tank.
The just is still out as to if it is better to hold affected fish like this in a acclimation tank, or put them back into the main tank.
This fish may have multiple issues (I ca see some white marking on its sides) In order to delve into that deeper, I need some background information, as outlined in this link:

Aquarists need to inspect their fish closely every day, for signs of impending health problems. It is much easier to resolve a problem when it first starts, than to attempt a drastic emergency treatment when the fish is close to dying.
