As promissed a few pic's of our three Limnochromis abeelei:
Presumed female 1:
Presumed female 2:
The only difference we (my wife and I) can see is the body height, which by the male is the heighest right behind his head. With the females is the back the most heighest point of the body and not immidiatly behind the head but is is still guessing because by venting them the differences are very hard to see. Male and female 1 are about 15cm (7") and female 2 is about 12cm (5"). We got female 2 from another shipment and when we got her she was a bit damaged by the other fish in the tank she was in at the LFS.
So far the three of them seem to get along as there is only occaisionally chasing but no real damaging eachother. The male seems to develop some what more interest for female 2 so far which is added 4 weaks ago.
