Does being a twin and and a gemini mean anything?

I have a twin brother, were look nothing alike. I'm 6 foot, dark skinned (a cinnamon colour), heavy build, on the other hand he's 6'3", a shade darker than olive. We are ying and Yang, night and day, salt and pepper. We have total different personalities. On the outside he is fire and I am ice, on the inside I am fire he is ice. We are complete opposites but the same. We both share artistic talents and also musical we were born left-handed know I am ambidextrous and he dabbles very little with his left hand. Most of all we are eachothers enemies but we are bestfriends we dislike and love one another. Together there is not one moment we fight whether its bickering like little school girls or an all out brawl. Right after black eyes, and bloody noses were sitting there laughing at eachother. I never met Gemini twins before, can anyone tell me anything about twin gemini, anything special?
