I hope I don't jumble anything up...
In germany, there were several animals popped out which are pretty similar to buf. NOBODY knowes if these animals are in fact the same as slangenbroed animals but I just wanted to say one thing, these "buf-like" animals popped out in a caramel line from breeding
hom. caramel striped to
hom. caramel striped, in the clutch weren't just caramel striped, there were also some strange butter stripeds which turned out to be very orange and not comparable to regular butter stripeds. the breeder noticed this difference and named them "Auratum" striped.
Another breeding, another breeder: pairing was caramelbloodred het amel x caramel striped het amel (same caramel striped line as above). In the clutch were animals which had to be hom. caramel but they DO look different. Phenotypically it's something between normal and caramel respectively amel and butter. It seems as if the inheritance of this auratum thing is similar to the buf: some kind of dominant! very weird!! but one thing is clear, there's something going on
pics here in these threads...notice the "butter het blood striped" baby on page 1 and the "caramel het blood striped" on page 2!

long story short: still more confusion
