Live food would certainly work best in getting them to breed.
I found this off a website:
"A lowering of temperature and barometric pressure, when done in conjunction with water changes, may very well induce spawning. Another trick is the feeding of live foods, especially Tubifex and finely chopped earthworms. Two or three males to one female seem to be the optimal rate for successful spawning.
Males will pursue the females until they show interest. The female(s) will then clean surfaces (mostly plant surfaces and the glass sides of the tank). There is then more courtship -- the male rubs against the female and touches her head with his barbels. Finally, they start the classic "T-position" during vibrations, which dislodge some eggs into the basket, which the female has made with her ventral fins. They're then fertilized and the female places them throughout the aquarium. There is a quick rest and then the males advance on the females once again. This continues for a few hours (two to three, usually) and the female deposits between 100 to 300 eggs.
The parents do not disturb the eggs or fry if well fed, but they might be removed after the spawning so that the fry can be reared separately from their parents. The eggs darken over their five to six day incubatory period. Finally the wrigglers emerge and feed on infusoria for a little while. Supplemental feedings may start within the first week and advancement to fry foods for egg-layers should occur at the end of their first week."
I imagine the hardest part won't be getting them to breed...hatching and raising healthy fry will be tougher.
