i have two silver aro's, on is 21" and the other about 15". at what size and age will or would a typical silver aro drop eggs?? i have read many threads and googled all types of info on trying to tell the sex of an aro. all of it seems to be here say, from what i can tell. i have been inspecting my aros closely all while doing the research, the bigger of the two sports a petruding lower jaw. all i want to know is when will one of them drop eggs if one of them is indeed a female??? i just want to know what they are already!!! also, what are the chances, if i do have a male and female, of them ever breeding in a 9'x3'x3' tank?? is it possible?? thanks very much
