First of all, congrats. You got the hardest part done. As for how to proceed it depends on what you want and how desperate you are for fry now. If the experience of watching them raise fry is important, I would think they will figure it out in a few tries. Every time I spawn something new, I am concerned it will be their last spawn. That has only been true for me twice. Cichlids usually turn into fry making machines once they get started.
If you really want fry now, then I would pull the parents and put methylene blue in the tank with an air stone. When I breed something, I want to hatch out I let the tank build up some algae then put a clean slate in so that is the cleanest spot they can put the eggs on. Then I can pull the slates and hatch them out wherever is convenient for me. You also get more spawns this way as they keep putting energy into making more eggs. Regardless getting that big bushynose out was the right call.
