Looks like an injury that has developed bacteria. Although the choice is maracyn 2, I would give it 90 min baths In ruby rally pro which is reef safe also

Is that a green conger eel? That seems to be a systemic bacterial infection. It isn’t normal for this species to lay on its side like that. If it remains that way, it is likely moribund (dying) and cannot be saved. If the photo was taken with the fish just happening to be that way, but it then swam normally, you might be able to save it by moving it to a treatment tank and dosing with a good antibiotic such as Neoplex.

He was dead at this point. I noticed him sticking out of his usual cave and looked like he had a full stomach. Then an hour later found him like this. Never seen anything like it before.

Since they hide so well, I wonder if the lesion could have developed unseen? Are you sure the "full stomach" was food and not ascites? Primary bacterial infections are rare, but do happen. I doubt that other fish in the tank are at risk, but keep an eye on them of course.
