@Jay Hemdal wondering if infection can have definitive signs that I'm missing, do you know? I believe the fish is showing no outward signs of infection, but thought I'd double check here. Probably you can't say one way or another, but worth another pass over this, appreciate your feedback, or anyone else who thinks they might know.
There are gas bubbles coming and going (as much as a few times a day?) around the base of his eye and typically extending out along the rise of the pop'd eye. You mentioned this sort of thing. I'm not talking about a lot of bubbles, but at least 3 that I've noted in the past 24 hours. One was small like a zit. This afternoon I see clear liquid half way circumventing his eyeball. I assume the bubbles are normal "blistering" or whatever equivalent it would be in fish injuries?
I do not see hazy eyes in terms of the pupil/eyeball itself. I've seen pictures of that on the web and he definitely does not have anything whitish like that "in" his eye, and never has. Normal colored eyeball.
The swollen rise that the eye sits on can appear to have a whitish hue all around the base/head, but it's mostly "skin" color and/or is not whitish and instead is clear liquid, in some areas with blood streaks.
So... what is concerning is that if I look at him with his body perpendicular to me (i.e. being in front of him), the mound and eye area in general looks hazy. But if you look at him from the side, looking straight into the one eye, the eyeball is clearly sharp and normal color.
He continues to swim about more than he was two days ago, but is still struggling to see and not at all his normal self in terms of bombing around everywhere or exploring. He stays very low in the tank- 5 inches off the bottom- and always in the back of the tank. That is nowhere near normal for him, but by the same token, he is nowhere near his drastically diminished behavior of Saturday/Sunday, and instead appears how one might expect a protective but healthy fish with an eye bulging out his skull to behave.
P.S. I imagine experienced aquarists rolling their eyes at the length and concern spilling out in this thread (pun intended), since apparently pop eye is not uncommon and in cases like this, typically does resolve on it's own. I suspect this fish will follow that pattern, he's a hearty devil. But for this owner... it's still a ghastly and frightening thing to see. If my wife came home with her eye sticking out of her head like this or I looked in the mirror and saw one of my own eyes like this, I'd feel like I was in a horror movie. But I guess for fish, no biggie.. happens all the time!
