Your going to need live foods to feed the fry. Vinegar eels, infusoria, micro worms, walter worms, and baby brine shrimp are all popular food choices. I would avoid using dried foods as most fry won't take them.
Before you breed make sure you know what your going to do with your fry. I noticed the fish you want to breed are VT and most likely from pet stores. It could be very hard to find homes for the fry so that is something you must seriously consider before breeding.
Also, make sure you invest in a good heater and live plants for the spawning and grow out tanks. I suggest using something like duck weed or java moss because it can be divided and put into smaller containers once the fry are jarred. Winter is coming up so something else to consider is how you will keep the fry warm once they are in their jars. You may need to buy a space heater unless your house is kept in the high 70s.
