Well Paul B. I do see you posting all over everybodies posts.
Yes sorry about that, I am a busybody and I am retired so I have some time to annoy people. :spin1:
Most people just think I am nuts.:hmm3:
I don't think adding Prime will hurt but Pop Eye comes from fluid or gas behind the eye, the cause is not really known (although there are many theories) but if you look at the skeleton of a fish you will see a smooth curved indentation where the eye fits and one little hole in the rear for the optic nerve. That area behind the eye does not get any blood flow and an antibiotic will not get there.
My fish have gotten it after they were in my tank for many years or just introduced, it is relatively common and in most, but not all cases it clears up on it's own.
I have cured it probably fifty times in my tank and wholesalers tanks. But I use a hypodermic needle if I need to cure it right away.
My last moorish Idol got it after a few years and my tank is not dirty.
I usually just stick a hypodermic needle in the stretched skin between the eye and the scales, not in the eye itself. This membrane is very stretched and thin in a fish with pop eye.
Then I pull back the plunger and the eye immediately goes back into place, no muss no fuss and I never lost a patient. Sometimes I inject an antibiotic in that space after I suck out the fluid.
But in your case, I would just wait a few days and see if it abates on it's own.
I know people get squimish over healing their fish.
