You're welcome. There the more dragon looking species of Atheris, and they don't do well in the hobby. In the wild they eat snails and stuff, and when you get them WC they already have a parasite in the lung that kills them. I know there's one person in Europe that has a pair, but other than that they're not in the US.
Now Atheris squamigera's are different and very common in the hobby, green being the cheapest color. Black's are usually the most expensive with blues/reds being behind t hem.
