Is it your snake or his snake? If you find a name you like and suits your pet, go for it!
I brought home my first herp a little under a year ago. A young crested gecko that was a beautiful buckskin tiger (and has since turned into a gorgeous Dalmation. Score). I decided to name him after food! It was a tie between Twinkie and Cashew. So I went with Cashew. My boyfriend hated it. But I kept it. Now he's called 'Cashy' and the name just fits. Even my other half will call him 'Cash'. He called dibs on naming the next one, however. So now I have Cashew the Crestie, and Quan Chi the Gargoyle gecko. Love it.
I like Rango too!
