Found this starfish on my live rock a few days ago, he's usually a green with purple stripes, but it looks like his one leg has turned a whiteish colour. I hope he's not dying. Does anyone know what kind if starfish he is? He's quite small but loves to travel. Is he reef safe? I don't have much coral, and no anemones, I'm mostly just concerned about my fish and if it's healthy to have one if these guys in here or if I should attempt to catch him and remove him.
