The tank bottom isn't important. You can change the water anytime. I'd change at least half of it. You don't need to vacuum anything, just remove and replace the water. Use a standard water change syphon and attach a piece of nylon from hosery to the end of the syphon with a rubberband. That way, you only remove the water and none of the fry.
The best food for your fry is frozen brine or mysis shrimp. If you can get frozen plankton in the pet store that's good too. The frozen food is much more nutritious than the dry or freeze dried. No additives!
If you haven't got some already, then get some floating stem plants like Anacharis into the main tank. Good protection for the fry.
Get the fry into the main tank in a week or so. With the good food, they'll grow quickly. Once they're all moved. Then start feeding all the fish a little more often. It's been my experience with "Livebearers", that well fed adults show little or no interest in the fry.
Just some thoughts that occurred to me.
