I don't know why, and I may get flamed for this but I think rainbow boas are butt-ugly. I just really don't dig the red-and black combo, plus the iridescence. SorryBut it does have a really cute nice face and nice slender body.
To each their own?
I absolutely love RTBs. I can't get enough of them. I love how clean their patterns look (even as adults) and all of the morphs are stunning. The first time I saw a sunglow at a reptile show, I fell in love.
