I have baby sword tails. Only managed to rescue two though because the other fish had gone into a feeding frenzy.... They were hiding in the gravel too.
I also had 4 ghost catfish fry that were a bit of a surprise... (thought they were egg layers and didn't think my tank was big enough for them to be hidden). Anyway they were a bit less cooperative and never managed to get any into the breeding net. Sadly none of them made it. And I only have one ghost cat fish so theres no chance of her getting pregnant again. I'm still confused as to how they got there in the first place - no male!!
