Given the Biocube design that would kill all water movement in the tank as it only uses one pump for everything. You could probably get by this with a small koralia or similar on low speed so they don't get diced. I'm usually pretty hesitant against raising fry in a display tank just because of how much stuff eats them that you don't think about, but they're so small they become bitesize for lots of things.
i didn't think you needed flow for raising fry. ive seen people with a 10g tank with a heater and sponge pump and that is it. just do water changes daily.
like fishtal said though greenwater will most likely not work in your cube so a seperate 10g tank for them would be good.
