Can anyone guess at the percent of males that will be infertile? Is it a high number or low?

It would interesting to know also how many male people think are sterile while the problem is somewhere else, like water in tank to hard.
You both have interesting points. Doesn't certain medications also hurt the fertility of fish too? I've seen tanks at the LFS where they automatically (or if an outbreak occurs) they treat the tanks. Maybe this will also have an effect on the possible fertility of a fish?

I never thought of that. If medicine was the case, then that explains why the eggs did not get any wrigglers.Quote:

I myself think most of the problems with eggs not hatching or being eaten before they hatch is mainly due to poor water,or like you said Rod lazy males not passing over the eggs properly.The actual % of infertile males would be very low.
