Hi David,

I imagine individuals can vary in temperament but the Mexican Red tail Indigo's I have encountered seem to be tame and not much different than Easterns when captive raised. Basically, rubidus is a more southern form of the Texas Indigo (rubidus, unicolor, erebennus, and melanurus) are closely related in the Drymarchon complex.

Yes, my male has that deep burgandy colored tail but only visible under strong light. Indoors the color the snake appears solid black.

Truly,
