Fish with a gas bubble in its eye

[untamed]

I've seen that before at least a few times with my Achilles tang. Always went away without intervention.

Oil slick on the surface suggests lack of surface water draw to sump or lack of surface breaking.

thanks for the info.

Yeah, sumpless tank, the koralia pumps were diverted away from the surface hence the lack of agitation, however the situation is now amended, I will keep everyone updated on the fish in case this happens to someone else.

is this different than popeye?

kinda, unlike popeye, the eye is not enlarge and does not portrude beyong the norm. It just looks like an gas bubble is stuck inside, over the pupil.
