I personally would be safe and separate them from other fish. I'm sure they're looking at them as food.
"Never let your krib fry be in the same tank as the parents for more than 2 months because they will take them as intruders in future broods, kribs will normally reach a sellable size at 1 inch fry can be pretty hardy. It is not unheard of finding fry living in filters!......Take fry out when the female starts to egg up again (when her belly looks very fat, almost like she swallowed a marble) she will view the older fry as intruders and will most likely attack them when caring for the new brood."
