I have hand spawned my ranchu

[planter]

I need help from bros here. This morning when I was watching my ranchu saw all of them chasing after one particular ranchu. I search online, this could be they are mating or eating up the eggs after the ranchu. I pick up the piece that was chased after and looked at the belly, it have eggs woosing out. I took a basin, filled up with the pond water and I started light squeeze the fish belly and eggs started flowing out. I immediately catch another ranchu that was chasing just now and I too squeeze the belly and white substance flow out. I mixed them in the basin. I have added air stone into the basin.
I need advise from here, have I done right for hand spawning? And what should I do next?
