As of this posting I've farmed up 9 of these pets.
I have not seen any other pet breeds spawn or be reported at this time.
After about 450 casts I was able to pull this guy up in the the pond/little lake in the Fields of Niuzao in Townlong Steppes.
I tried over 1000 casts in the Sha-Touched Waters near Binan Village in Kun-Lai Summit without success.
