These are some of my Yearling Brazilian Rainbows. The two dark females were very dark and seemed to have no red pigment when they were born so I held them back to see if they might be anerythristic. Over their first year they have gotten some red coloration and thus are just normal dark BRBs. They bth are more black and less red than they look in these PICs. I held the males back because they have the orange color and bright crescents I like. All of these snakes are around 36 inches long.
