XR is completely right about jags how they pop fry out like no tomorrow. I would say they are more so than cons. Even though mine took about 1.5 months to lay, I now have over 1200+ managuense growing. It's insane how they lay but I think I take the cake on most eggs at one single time. I have never seen a manny lay as many eggs as my female does. She lays about 2000 each time and my male can fertilize all but about 35 no lie. I'll find pics.
Oh and mine lay every 2-3weeks.
