The Boxing Crab is also known as the pom pom crab which is a small crab that is no larger than a quarter. Its petite size makes it a valuable addition to any mini reef tank. The Boxing Crab has a white body with darker area that provides a camouflage effect. It carries a small anemone in both front claws which looks like pom poms that serves as a form of protection. It shakes the front anemones in hopes of stinging the invader into retreat. The Boxing Crab shows a very unique symbiotic relationship, in which the crab can be seen in moonlight swaying the anemones side to side collecting food for itself and the anemone. It is reef safe and may be aggressive towards other inhabitants, and should be kept in tank not less than 20 gallons. This is undoubtedly a very pretty species with a mosaic of colors adorning its carapace. The Boxing Crab undergoes molting and sheds its exoskeleton in order to grow. It mainly feeds on algae pellets or sheets of algae if it is unable to find enough food in the aquarium. The Boxing Crab is named aptly, since it will box the anemones if attacked as they have the ability to sting.
