Jack Dempsey's

So I jus got a female jack today for my male that I got from CSnyder00.
What are some signs that they will spawn?

As of right now that are chasing each other around even locking lips.

I think those are good signs hope for the best. My turquoise fish use to do that and lay fry but they would never hatch I think the male never did his job..

Those are good signs. As long as they aren't hiding from each other. Eventually they will start to pair up.
