It depends. I think they'd be fine for a while, but be prepared for fighting between the male and female after the fry have hatched. Mine got in arguments and didn't seem to like each other very much, but I also had plenty of dither fish in the tank so eventually the couple paired back up to take care of the fry. So, you could try it, but be prepared to move one of the adults if they decide they don't get along, or at the very least, provide *plenty* of plants, driftwood, and rocks/caves with different hiding areas at opposite ends of the tank.
At about six weeks of age, my last batch of fry had developed their adult coloration (although not quite their mating colors), had become independent of their parents and mostly of each other, and had even gotten to the point where they weren't getting along with one another. The fish averaged about an inch or 1 1/4" inch at this point, which was when I decided I needed to get rid of the fry. This size is smaller than young kribs are usually sold for, so it might be difficult getting a good price on them at such a young age. However, you should be able to give the fry away at the very least.
