Marius in his evening attire (pic heavy warning)

[PyramidPythons]

Wow, his colors and markings are amazing! Gorgeous animal, thanks for sharing!

Thank you, and thanks for commenting.

So I have to ask - Do all BRBs get the white sides in the evening? And can you trick him into changing into the white sided pattern by cutting out all light from where he is at? Very unique trait in a snake, to say the least!

As far as I know it is a BRB trait (though I couldn't tell you if other species of Rainbows do it). I have not tried to trick Marius into changing to white by keeping him in a darkened room (that would be an interesting experiment and I might have to try it, lol!), but I have noticed that he is most bright white closer to when he shed and as he grows closer to his next cycle, the white lessens in brightness.
