I have some questions about my Syno Petricola Dwarfs

1:
is it possible to see the difference between male and female, and wat are the differences.

2:
What is the maximum life span of this species

Those have a scientific name in , and I think first question is answered there. Second question I would guess "ten or more years if cared for correctly".
