Just as the post stated so I’m currently out the house so I can’t take a picture right now so I went to my local store and they had this small crab that they had no clue what it was it’s all white with a little pink on the bottom and bottom tips of it legs but otherwise completely white with bright purple rings around its claw I was wondering if anyone has any clue what it is they had it with sand shifting snails if that helps any with Iding it

So I was able to ID it my self it’s a (Carupa tenuipes) / violet eyed swimming crab I think it just has got its spots yet
