10 Gallon Breeding Tank

[Questions?]

I now have an empty 10 gallon tank. I wanted to dedicated this aquarium to albino corydora catfish. It has a sand substrate, 2 fake plants, i will try and add some more live plants( i need some ideas) do i need any rock formations? Also i really want them to breed, so is there a certain setup or someting i need to promote breeding. Also should i add some kind of rock formation for the eggs or something.

It already has a 50 watt thermometer and a slim filter that is made for 15 to 20 gallons
