a friend of mine has a few actual imports from there, they are massive and have a higher tail than ours do, well at least hers did...very beautiful birds though.
That's the funny thing about sumatras, just as that book listed a few post back says, there are several "styles" of them. The show standard calls for one thing, but these others are still just as much sumatra as they are, just from different regions. Main difference is tail design that I have seen.
