Ado,
I have a pair here mate they were sold to me as Checkerboards male is about 15cm and female is about 10cm I have had them for 12 months and I was the first one to put them together but in saying this not sure of an accurate age.They have laid quite a few times but I have not had the time to get things right with them, they sometimes eat the eggs I think this could be fixed with caging and spending a bit of time with them.I'll try to get you some photos.
Norto.
