This is the first time I've tried two virgins. I am actually surprised that it worked. I thought I'd introduce them, but that it would end with no success. When they seemed interested in each other, I thought "maybe" but they took a bit to figure it out.lol The only advice I can give is make sure the female is very eggy! And I guess just be patient.lol
It is funny watching the Dad now. He even flares at me when I get down and try to look up into the nest. I cut a Mcdonalds Styrofoam cup in half, and he did build his nest in it. And man what a nest.lol It is coming out the end, and almost fills it to the top! The only real way I know he has eggs is because I saw him collecting them and spitting them in the nest.
Good luck with your spawn!! Let us know how it is going! As soon as mine are free swimming I will start a log. I actually have two spawns that happened today! I was thinking if the giants didn't collect, I was going to try to sneak them into the other spawn nest. Luckily, they figured it out and collected them!
