Determining the sex of my demasoni

I'm still having trouble figuring out the sex of this fish, lol, I know I've had issues with this in the past, but I'm hoping someone can help me out this time.

Egg spots are typically a male trait, so you're on the right track there. How's the fish behaving, any aggression issues? What's the rest of your tank's population like, got any other fish in with him?
