Jeff, I know a German breeder who is breeding outstanding Vietnamese Mandarins (check out his website at the link I posted below; mind you it's entirely in German) and has shipped some of his Sichuan offspring (he also breeds Sichuan Mandarins) to the United States. Forummember John Firneno ( "jfirneno" ) has recieved some of these. However, there is a waitinglist for Vietnamese Mandarins already in Europe. Early 2005 I got a CB 2004 male from the mentioned breeder and I am still on the list for a female! In general Vietnamese Mandarins seem to be slightly more difficult than Sichuan or "Eastern China" Mandarins. The hatchlings are frequently problematic feeders (my male for example didn't feed voluntarily during the entire first year; now he's feeding on live prey items, but still not very consistent) and the adults are more difficult to breed. It's not standard that they will breed annualy once they have reached adulthood.
Fortunately, you've got amazing Sichuan stock in the U.S.A.; I haven't seen them as stunning here in Europe. I think that the European stock tends to darken considerably with age.
Regards,
Bert
