I have two chinchillas, one named Audacter (Beige) and one named Hebenus (TOV Ebony). They are brothers, and were born on October 8th, 2003. I got them from a local breeder of good repute. Audacter, whom got his name from the latin word meaning adventurous, is, as you've guessed, the more adventurous of the two. Hebenus, which means "ebony" in latin, is more conservitive and is content to let his brother do the exploring for him. Although, he does have a tendency to take bigger jumps then his brother.

You can see pictures of them here.
