I know that you need to provide a still tank with plants so that the male can build a bubblenest, and also so the female can hide if the male turns nasty
you also need to feed up the female until she is ready and then add the male to her, he should then display off his fishhood, build a bubblenest and squeeze out the eegs from her, then he catches them and places them in the bubblenest.
unfortunatly when I was trying to breed them, I always found that as soon as I put them together they would try to kill each other, but I did get a couple of bubblenests being made.
I also plan to try to breed these fish sometime soon.
and as for feeding baby fish, I sometimes use the "baby food" available at any fish shop, but what I usually do is mix up all the fish foods in my house and grind them down into very fine powder, which I find is great for baby fish, and its also nutritianally very good.
