The traditional "wisdom" has been to have at least 2 fems to each male to
reduce the aggression directed to them individually. Ths aggro varies
condiderably between individual males and of course from species to
species. Incisus have a rep for this problem.

It helps to make sure that females are well conditioned before hand and try
to have them at least as long as the males if possible. BTW I have had
large female Incisus be just as aggro as males especially to smaller fish.

The topic of "reverse" trios is interesting - some of the Killie folk use
it and I have tried it at time with Blue-eyes with some success especially
if they are being a bit slow producin eggs. Theoretically a surplus of
males could stir up the display reflexes and induce spawning - I would
suggest trying 3 males to 2 females. While 2 males are busy displaying
perhaps the spare coud be entertaining the "ladies".
