This species isn't really hard at all. I have around 30 fry from them currently and lots of eggs.
I just put a layer of peat moss in a 500ml plastic container with some java moss and IAL, then fill it up with water from the main parent tank. I put the eggs I have picked off the mop in, and add a drop or two of methylene blue to help prevent fungus. Running an airstone in there can also help with that.
Then a couple weeks later I should see the fry starting to hatch (you can see their eyes through the eggs) and then their care is quite similar to that of any fish fry.
