Daniel, Be patient, all Pelvicachromis species are slow to pair up. It took my Pv. roloffi almost a year, my Giant Kribs over 6 months. Usually Pv. pulcher that you can sex will spawn within a couple of months of being placed in a tank. One thing you can do to encourage bonding and spawning is to bury most of the entrance to each breeding cave with sand or gravel. Digging a breeding cave by the female seems to a be behavioral stimulus to pair bonding and eventual spawning. Mike Wise Daniel Boyer wrote: > How do you tell when Kribs are sexually mature?
