Decided to show off anon’s ‘muddy snakes’. The top left is a green/silver pair, top right is clutch results.
Freitas also created the oxyjansen hybrids, in which he theorized that the jansensi was just another color morph of the oxycephala species (second row images is pure jansen, sulawesi and selayar pure black). The resulting snakes hatched out green and ‘normal’, and would go through a color change to the amazing adult you see at bottom. IIRC, the hybrids were also calmer animals like their janseni parentage, and were pretty easy to keep.
