If you can rig a fry tank that would increase the survival rate as well. Live plants help tremendously but you CAN get away with plastic (yuck) as long as it is dense and the fry can hide in it without fear of predation.
Fry like floating plants as mentioned above but I had a tank with anacharis that had strands over 3 feet long. Since the tank was only 16 inches deep a lot of it floated and the fry seemed to like it, plus, I could cut pieces from the longer strands and just stick them in the substrate and they would grow (who doesn't like free plants?). Micro swords, dwarf hairgrass, and bacopa make pretty good fry plants too.
Why do I love fish? Because every time I stare into the little world I have created for them, every problem I have just floats away....
