The male is not fertilizing the eggs.

Hello, i have a beautifull pair of Blue cobalt, up untill the last treatment for flukes with fluke tabs they were very successful in having baby, but now the eggs turn white and no babies in site.
Is it possibe that my male has become sterile.
Regards.

Probably not. Have you changed anything else - more current in the tank, raised heat? IS he making passes over the eggs? You had wigglers and live fry before with this same male and female?

Yes i had, and after the treatment everything was back to normal exept no live babies anymore.
Today i switched the male and in a copple of days i'll see, it seams that they get along and the male has a lot of interess for the female.
I keep you posted and thank you for the reply.
