So Viola is a 4 1/4" Redfoot juvenile. She looks, by all standards, 100% female to me. However I started to read that since they are still so young when sold (as compared to the age of a similarly sized adult Russian pet stores sell), they are technically still too young to show much sexual dimorphism. So technically, Viola could actually be a Victor or something.
I was wondering, at what size do they start to develop differences between the sexes? And is there a blood test or some sort of test a vet could do to determine Viola's actual gender this early on, like they do with hatching birds?
She has to go in soon for a checkup on how her shell rot is healing up, and if there is a test the vet could do, I would really be interested in doing it. In the future, I would like to get her a companion (as I read they tend to like to be in little herds, rather than be alone), but I want to make sure I don't get two males or anything by accident. I'd rather not have tortoise fights! x___x
