I can faintly see a little shaded patch where the black splotches are on the picture you provided, but it's not nearly as dark and distinct, but at the same time, he's not as young as the one you provided I'm assuming (looking at the size of the eye in comparison to the rest of the body) Is there a certain age where that spot disappears, or is it permanent?
I'll try to get a closer shot of mine, but keep in mind my tank water is kinda brown stained with meds. The green terror isn't sick though. He never gets sick
