Clown Killifish - Breeding Care? Help Please.

[totally tropical]

I have 10 very small clown killifish and have set up a spawning mop for when they and my furcata rainbowfish may at some point lay eggs. I also have lots of floating Hornwort, not sure if they may lay eggs on these plants also?

Please can you tell me what colour/size the eggs are and an a-z step of how to manage/care for the eggs in order to hatch successfully? Also any tips on how to care for fry? Any info would be greatly appreciated.

Thank you in advance.
