The Purple Lobster is a relatively new item to become available in the aquarium industry. These Lobsters have incredible coloring that begins with purple and extends to violet, pink, shades of blue, and yellow. They will not harm or attack other invertebrates or fish, unless provoked. Purple Lobsters prefer lots of hiding places, crevices, and caves, so it is best if you have lots of rockwork in your aquarium. The Purple Lobster is nocturnal and should be fed meaty pieces regularly to prevent predatory feeding habits, they will also accept flake and pellets. Keep only one per tank. They make a great addition to any aquarium.Lobsters belong to the Class Crustacea and Order Decapoda, which is characterized by two pair of antennae, three body parts, and five pairs of legs. The head of a Lobster is connected to the thorax and covered by a shell called carapace. If a Lobster has antennae they are normally thick and conical and serve the Lobster as extended eyes. Lobsters normally have thick and wide abdomens and tails which allow them to propel their body backwards at lightning speeds. In order for Lobsters 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 Lobsters will leave this translucent shell in full view so it can serve as a distraction while the Lobster finds a hiding place as its new shell hardens.
