First If I want to raise them to the point of being able to sell/give how many tanks am I going to need.
It really depends on how many fry you intend to raise. You could raise quite a few with just 2 or 3 tanks.

If I do need another tank will a sterilite container be safe for them?
I have kept all kinds of fish and fry in sterilite containers with very good success.

What type of filter should I have in the tank where they breed.
I use sponge filters in both my breeder set-ups and the fry tanks. These fish come from shallow still-water ponds and don’t require much water movement.

Also in the tank for really small fry do I need a sponge filter or will just an air stone due?
If you are going to raise the fry in this tank, you will need some sort of bio filtration. Sponge filters are perfect for fry tanks.

…..and lastly could someone recommend a good food for them.
I use both Golden Pearls and Sera Micron prepared foods. The Golden Pearls comes in sizes from 5-50 micron all the way up to 800 micron. Best of luck with your breeding project!
