Riv. sex ratios?

Yes, he does pull the eggs ut and water incubate them. But the species he
works with is agilae, and I work with uropthalmus.
> You mention "your friend here"

>Finally can you tell us a little more about your water conditions, pH,
I am one of those annoying people who hardly ever checks their tanks pH
I know the water comes out of the tap neutral and soft. And when I neglect my
water changes the water presumably goes abit on the acid side.
Temp: I rarely use heaters so the room temperature dictates the tanks temp.
Over a year period ( in which I collected the 17 fry; 16 female 1 male),
changed between 18 to 29 degrees Celcius. Therefore the sex determination
temp influenced in this case (I guess).
I have been hatching quite a lot of Riv.cryptocallus eggs lately, which I
and incubate in straight tap water (with chlorine and all :) ) and will be
recording the sex ratios of the fry in the coming months.
If I figure out how to collect the uropthalmus eggs that might also give an
