my brother had a rose haired tranch.. it was very rude.
it always stood on its back legs and showed its HUGE fangs when anyone went near its cage...
I really dont much care for them.

they dont live long either. and they are very expensive...
my brothers only lives about 6 months before it croaked.

one time it escaped.. it was creeping across the kitchen floor, my dad almost stepped on it... EW.. that would have made a big squish!.... *barf*...

anyways... good luck with your researching.. i hope you have a better experience then i did... gulp.
