Couple close ups of head region. He is going in another tank with substrate and dimmer old T8.

Appx 9". His lines on his head a barely visible.

So because of the black base his colors are normal? I know at one point he had yellow tips at the point of his dorsal and ends of his pectorals.

As title says, imported as 418. But some thoughts 191?

Have a 13" Luteus with a second coming next week. I was wondering how to identify whether male/female of the species.
