My last spawn of njisseni came after I let the pH creep up a bit, then dropped it. You might also try some competition, although a 10 gallon is a small apisto tank. Dithers will sometimes trigger spawning. I find if I put a breeding pair of any apisto in a tank beside njisseni where they can see them, they get territorial and then get active.
