At the ST Louis convention I bought two bags of Cpl. brucei. each bag
contained 1 male and 4 females. I thought the sex ratio must lean towards
females. One male died and 2 females died. I placed the male with 6 
females
in a small tank with peat moss in a container. I had good success with 
them
and was happy when I saw some of them developeing the red tails. I 
confidently
listed them in the BNL. When they were mutured I had a hard time finding 
any
females. I did manage to find 2 which I placed with a male. I got eggs but
the hatch was nil or very poor. They are just sexing out now but I know of
one group of 4 where I have 1 male and what appears to be 3 females. I did
change to RO water from some that I had cut to 100 ppm on the first 
group. 

I realise that this is just a small observation and is not very 
conclusive and
there are more factors involved
