Welcome to Pet Talk!!
Your new chin is beautiful. I have 3 chins of my own. My I recommend a great food for him... Oxbow has a great chinchilla feed. Most other brands are "junk food". You can order it from the site if there isn't a store near you that sells it, that's what I do.

Also here are a couple more hawaiian names:
Keiki (pronounced Kay- Key)- it means child
Kapua- means flower
