Grouper single eye Popeye

[Miller Aquatic]

I got this cherry grouper may 5th and I put it through three rounds of prazi pro and it was going fine but then I used copper power at 2.2-2.4 and all of a sudden his eye got huge and developed pop eye. It looks like a bubble on it and I dosed marcyn in it with the copper power and it didn’t do anything but I didn’t know if it would be different with the copper since it’s an immunosuppressant? I don’t know if I should discountinue copper and use just the marcyn or what to do it’s not cloudy at all and only one eye but it may be bloody/red but I can’t tell because of the color of the fish.

This is either from an injury or gas embolism. If injury, treatable with maracyn as pictured below but seems to be air bubble and wait a couple of days to see if it subsides.

Agreed - this is either an injury, or less likely from gas supersaturation (that usually involves both eyes)

Maracyn 1 helps with possible secondary bacterial infection, but timenn be is the best cure for this - it can take a month or more, and in some cases, the fish ends up losing the eye.
