I came accross this on youtube, I'm not sure, but his eyes don't look too healthy? Penn, what do you think.

I am undecided to whether that is actually pop eye disease or not. Some Oscars have got very prominent eyes. I am going to study the video a bit more.

Im not sure. Its eyes do stick out its just whether its pop-eye or not. All fish vary, it might be just the way he is. Off course if you owned the fish you would know as you would notice the eyes getting bigger very quickly. I guess we just have to trust that the guy who owns the fish wouldnt put it up on you-tube if the eyes got bigger over the last few days.

That oscar is very aggressive isnt it. The other one hides away
