I am new to the world of sugar glider and still don't know all the colors yet. My female is about a year and she is much more colored in her face than my other two classics. I just got all of them these past few weeks. Two classics are very chubby and friendly. This little girl I'm still working with. Is she also a classic? Her tail is much more full and fluffy than the other two as well and always in a little curl at the end.
