Depends
Congrats! Are they in their own tanks or community tanks?

The C123 were in a community tank, and spawned within a few hours of being moved into their own 20L (except for a few RCS).
I moved the Bolivian rams from a community 55 into 20L about a month ago, but with some neon tetras and male Endlers. Their first spawn disappeared and the tetras looked guilty to me, so I removed them. The rams spawned again shortly thereafter. The male Endlers are too busy searching for a female to have time to eat the fry, I guess.
The kribs are in a community with some corydoras and female guppies, both of which are trying very hard to stay out of the way of the fry and their parents.
The rainbows are in a community tank. The only fry that survived were ones I removed to a 5 gallon grow out tank. I have another rainbow pair in another community tank that also laid eggs, but I never saw any fry. Of course, at this point, I really don't need more fry!
