The female who kills the males? That sucks, I am so sorry for the loss. I think my male krib is attacking the female now... From breeding rams, I found this usually means the female messed up. My best pair always started fighting when the eggs turned to wigglers. The male was the aggressor, to me it bacame obvious he was trying to protect the babies from the female who must have been eating them. I may end up getting two new pairs of kribs all together. I will see how this batch of fry turns out in the end before making a final decision. I may just end up getting a group of juvie kribs myself and letting them pair naturally so the pair doesn't have so much tension.
