First timers: A larger male paired up with a relatively young JD female who laid eggs. I removed their tankmates as they were behaving quite territorial and was worried about the fry being eaten or the tankmates being beat up. It's been about 4 days and the eggs haven't hatched- some are white. Looks like they failed. Should I just leave the two in the tank alone and wait until they spawn again? Or should I put a fish or two back ? How long might it be until the female lays eggs again?
