Kribs will be fine. BTW we're talking about the standard Pelvicachromis pulcher.
Kribs are suited for standard community setups. Apistogramma prefer loads of plants with natural wood and substrate, or a biotope aquarium with dead leaves, wood, and tannin-rich soft acidic water. They are easy to care for, but only if you are prepared to meet their needs. If you just chuck them in a standard community tank they are not going to thrive. Whereas P. pulcher are pretty much bomb-proof, and are a great beginner's fish as they don't really have special requirements except for a couple of retreats and decent water quality. Just make sure you get a good tank-bred strain though, because in America there might be wild strains for sale and they need to be treated just the same as Apistos.
