Answers:
Is this a Red Top Kimpuma? The name is spelled Labidochromis, so you may find more info if you look them up using these names.

There should be a color difference between males an females, with the dominant males being a brighter lavender and the anal fin coloration should be yellow with a black stripe through it. In females and submissive males, the body would be duller, either brown or pale lavender, but the anal fin will let you tell these apart. The females have an anal fin that's just black with some white along the front edge. So you should be able to determine the sex if yours are both adults.
