Good name for bearded dragon?

I'm getting a Bearded Dragon In about a week and was wondering what I should name It. I was thinking If It was a male a cool name could me Slash Axel or Blaze If It was a female some cool names could be Nikki Elena or Athena. Which one do you think Is the best If Its a boy or girl. Also I was wondering for a baby would a 20 gallon tank was good or I could just put a 50 or 60 gallon tank so I don't have to get another one in the future and he or she would be set.
