These animals need to be adopted. They are in great health, but do not meet our standards as being perfect. They are either missing a claw or a leg.Perhaps one of each. Over time they will molt and grow back. We just do not have the room to continue to hold them in our systems. This is where you come in, we are discounting them so that you will adopt them and take care of them. In time you will see that they will be perfect again. These Anemone Crabs are brown and orange in color. They are very peaceful and more than one can be kept in each tank. They have a symbiotic relationship with Anemones, and will accept most Anemones as their host. They cling to the base, underside, or on the Anemone, without causing tissue damage. Anemone Crabs do not need an Anemone to thrive, and are a great addition to any reef tank.Crabs belong to the Class Crustacea and Order Decapoda. Hermits and Porcelain Crabs belong to the Section Anomura, which consists of long antennae and three pair of walking legs. The head of the Crab is connected to the thorax and covered by a shell called carapace. They have a smaller abdomen and tail compared to Shrimp and they keep this tucked beneath the carapace. The first pair of their legs are usually developed claws which they use to gather food, use as protection, and to move objects. In order for Crabs to grow they need to shed their exoskeleton, a process called "molting", which allows them to remove their restricting shell and begin a new one. Often times in the home aquarium Crabs will leave this translucent shell in full view so it can serve as a distraction while the Crab finds a hiding place and allows its new shell to harden. Hermit Crabs use abandoned shells as their home. These Crabs usually have extended abdomens that they wrap around the inside of the spiraling shell leaving only their head and claws exposed. When approached these Crabs can recoil into the shell for protection. When a Hermit Crab grows it will often seek out a new larger shell.
