Hi all,
First the disclaimer that I'm not very good at this, and although I kept A. cacatuoides through multiple generations, I still ended up selling "pairs" that were the same sex.

Last clutch of fry seems to have all females at what point in time can you tell sex

You can tell when the males start to grow dorsal and caudal fin extensions. The ventral fin edge also helps, females and juveniles have a black leading edge, but in male juveniles it starts to fade as they grow. Have a look at <"Sexing Apistogramma....">.

and fried cockatoo 80 how do you get more males is there a way?

Sex determination is temperature dependent, higher temperatures give more males. I found about 27oC gave equal numbers of male and females.
