Oscar fish

[Oli]

Looking at getting these lemon Oscar’s, unfamiliar with lemons though. Do these look healthy, regarding the grey patch on the head?

That looks like pigmentation to me.

I agree with Gary. It just looks like some cool coloration

Really interesting fish. Puppy dog fish with interesting color, I am jealous.
