Sex ratio "controll" in P. taeniatus "dehane"

[Fisherking]

HI, after a 2 year breake in the hobby I am starting up again witha a new fish room.

So, as the title says, how can you control it. In apistogramma it is now problem since romer wrote it in his book, and it work in some degree. But what about P. taeniatus?

I breed my fish 6.5 - 7.0 and get ratios close enough to 1:1 to say that there is no effect. I cannot speak to breeding them in parameters far outside of that range.
