Welcome to Aquaria Central! From what I have heard/read it is almost impossible. They breed in the middle of the night with the female and male rushing to the surface with the female depositing eggs on the surface and the male right behind fertilizing, but the parents provide no protection so you must get the eggs out immediatly. There was a article about this I think about a year ago in Tropical Fish Hobbyist magazine which you may want to check out if you can find it. It talks about a person that was able to breed them and how he did it. Hope this helps and welcome.
