Milo,
Thank you for the insight! I picked her up yesterday after spying her at a local shop earlier in the week and falling in love with her colour.
The shop owner was adamant that she was a salmon, but I was sure this was not the case. (don't worry, I didn't pay a salmon-price
)
Because of the general misinformation that is routinely flung around this particular extablishment, I am unsure of her sex or age, though they said she was female and around three years old.
I plan to get her properly sexed when she comes out of quarantine. 
So that's two votes for CA and one for Columbian. I tend to lean toward the CA myself, but I'm definitely no expert!
Thanks again!
