Im kinda confuse about the sex... I always though mine could be a female but... I see now male characterists than female ones... have you see the pic of Lili what do you think?
How long is Lili? Until the shell is about 4" long you can't really tell.
I can't quite tell from your picture, but it sort of looks like Lili is growing a pretty long tail, like a male. However, her/his nails are still pretty short. It may be that she/he is a male in transition (puberty) and his nails may start to grow soon. My understanding is the tail grows long and thick before the nails sprout out.
