She is old enough to spawn now, but whether or not the male you pick, will be acceptable to her, may be another story.
Just because there is a male and female, doesn't mean they will spawn, even if you get a pair that has spawned in someone else tank, doesn't mean once moved, they will still spawn in another tank.
All cichlids have complex rituals they follow before accepting a mate.
I do think she has good color.
If it were me though, I'd get 2 or 3 more females, and one male, and expect the male to kill at least one, maybe 2 of the females before a pair is formed.
Usually I get 5-8 juvies, and let them grow up together, naturally selecting their own mates.
Just an aside, to me, a JD/salvini hybrid would be worthless.
