Congratulations! I can imagine you're happy as can be now after so many failed attempts!
Funny thing that, about alpha's not always being the best caretaker. One should think that would be one criteria of becoming an alpha, that the females would choose him because they knew he was the best one for the job, and that he himself would think so too as he wanted the role in the first place! It's all about making sure your genes get to live on isn't it
But we've seen several examples of this not necessarily being the case... If you relocate the alpha the other male would most probably step into his shoes - and get all the ladies

That way all those precious eggs won't go to waste!
