Re: [Killietalk] When is gender determined?

["Bill Shenefelt" <william_shenefelt at verizon.net>]

I know Curt Smith has had good success raising fry in twosomes to get pairs, 
but this is with South American annuals.  Similar results have bee reported 
with Nothos, but I have not seen anything similar reported with the West 
African Aphyosemions.  I have tried it with no success with Aphyosemions. It 
may work but not for me with whatever conditions exist in my water and food.
