That's mad! We have a Brazilian Rainbow boa and Tink is FASCINATED by him - she'll sit there whining at the cage if you're doing anything with it. However, the one time they got anywhere near eachother, Hades struck at Tink, so I don't think we'll ever be reproducing your pic! I had him across my shoulders while I was rearranging his tank and didn't realise that Tink had jumped onto the bed and was standing right behind us! I just felt the "snap" when Hades struck out. He didn't get her, though, and she didn't seem a bit fazed by it.
Hades is actually the most chilled out snake ever (which was a pleasant relief after our last one, who'd strike if you walked past the tank!). He has never even struck at Emmet or I, let alone actually bitten either of us. (Touch wood, ha ha!) I even fell asleep with him up my sleeve once, and when I woke up I literally had to shake him very roughly out of there (looked like I was doing the hokey cokey!) and he didn't even flinch.
