Our Chancre Crab (aka. Brown Crab, Edible Crab, Pastie Crab) enjoyed a feast recently. We had found a washed up fish-box that was covered in Gooseneck Barnacles. I scraped a few off the plastic box and strung them up our little marine aquarium. They were fascinating to watch — sieving the water for food then retracting into their shells to eat. That was until Chancre got wise to them and decided to get piece of the action for himself — even moving rocks so he could reach them!
