Approximate Purchase Size: 1/2" to 1" REEF SAFE $2.99 each Quantity :  Pom Pom Crab Lybia tessellata Description: The Indo-Pacfic native Pom Pom Crab is a comical aquarium addition. This unique crab species carries a small anemone, which look like pom poms, in each claw. There are at least two purposes for carrying the anemones. The first is a simple matter of defense. The Pom Pom will taunt would-be predators by shaking the anemones in hopes of stinging the invader into retreat. It also mops the substrate to gather uneaten food, thus creating a symbiotic relationship between the Pom Pom Crab and its pom poms. The anemone undoubtedly benefits by getting to eat its share of the treasure. Also known as the Boxer Crab, it is a hardy creature that grows to about an inch in length. Because of this small size, it is great for the mini-reef aquarium. This crab is attractively marked, with striped legs and bold markings. The anemones are dropped during molting but are retrieved once this process completes. Curiously, lab studies have shown that a crab that loses one anemone will attempt to split the one it has into two regenerated clones, a method used by humans to propagate larger anemones. They may be kept in groups and females will produce reddish colored egg masses that they carry on their abdomens. Food and diet: They can be fed algae pellets, or sheets of algae if they can't find enough natural food.
