Brichardi behaviour

I have half a dozen Brichardi of varying sizes in a 20 gallon tank. For the
past few months they have all been the best of pals. However I now have a
whole lot of Brichardi fry in the tank too. Four of the adults still get on
fine, but they have all turned on the other two, so that I have had to
remove them to prevent them being killed. I can understand that the fish
might get more territorial as a result of the young, but I don't understand
why these two would be perceivd as a threat and yet another two who are not
the parents are seen as ok. Anyone have any ideas?

N. brichardi are colony breeders. The two that are getting along fine with the
two that have bred, may be accepted females, brother's and sisters seen as part
of the colony or adopted relatives. ;-) The two that are being harassed and
would be eventually killed obviously weren't welcomed to the family. Once
breeding begins and the group is hashed out, after the initial on slaught of
violence, the only violence to follow will normally be directed towards the non
brichardi tank mates. From now on, they should live as one big family unit
together creating hundreds and hundreds of fry day and night non stop like
little Tanganyikan rabbits. =)
