I have a yuma that looks just like this. Purple base with yellow tentacles. This picture is completely saturated in blue so keep that in mind. I paid $15 for a small one, but I buy most of my stuff locally.
Good looking ric. Orange Yumas like this are seen alot out of Vietnam. They usually come on a rock with a few larger ones and a few babies. I see rocks with 3-6 around for $50-60. Single ric like that around my parts would be priced retail at $20-30.
