You asked a very difficult question ! I really had to think about it. Although my absolute favorites are actually multiple traits (amber, ghost, and hypolav), I had to choose aneryth as my favorite single trait, with amel running a close second. These 2 morphs come in such a multitude of shades and variations that you can own many snakes and no 2 would be alike. My own aneryths range from being almost a ghost in appearance, to numerous shades of brown with some pink undertones, to solid black on silver. And then there are the aneryths combined with the pattern morphs!
