Fish Herder
When I bred the first concern was that the male was always terrorizing the female and never built a nest bigger than 20 bubbles or so. She got nipped pretty good and spent most of her time buried in some java moss. Four or five days later they were spawning perfectly and making the nest just right.
The second concern was that the fry were either being left on the floor or that some of them had worked their way up on top of the bubblenest so they weren't even in the water anymore. The male ended up making an entirely new bubblenest somewhere else in the tank (not under anything) and moving every single one of them over. I don't know why he did it but it worked beautifully.
The third concern was that I started with a big grow-out tank 1/3rd full, and once they scattered I had no idea if they were finding food or not. I could only hope they would find the worms wriggling on the bottom somewhere. As I said, I've had even fewer casualties than average so far.
You don't have to worry... nature knows what it's doing.
And if these things had turned out to be actual problems, worrying wouldn't have affected them one way or another anyway. If anything it could have caused me to mess with things and screw it all up.
