| I found some photos of female vents on our teenage son's laptop, but threw them away and didn't save any for you. Anyway, it would be unpleasant for you and the fish to keep checking her vent for signs. If you are keeping the sexes together, the male will start following the female about a week before the spawn. The following will turn into chasing as the day approaches. That's a pretty good sign and doesn't require handling the fish.
