Scott...no taco. You forget the rules of the game. This is in a bath tub therefore (playing the odds) will be light colored, but a snake with say "black speckling" in the red (as most corals do have) would still not look vivid red.
As to langsdorfi, My pictures (from 4 seperate books)show a snake that is not predominently red and yellow. It has small yellow bands and black speckling on the red. That doesn't fit the description. Also she said that no color was predominant. That all bands about the same size so that does not fit the description either. Unless you are refering to a subspecies I have not seen that snake qualifies even less than an American.
Actually the only one that comes close in Corals would be the Arizona coral M euryxanthus (which fits the criteria) But it would have to be a Mexican specimen as Arizona (I beleave) does not allow collection.
As you said the odds of a coral are slim. The odds of a rare or unusual coral are about zero if that.
So the initial band count rhyme I mentioned still is valid.
