Regal Slipper Lobster
Regal Slipper Lobster, Arctides regalis, is a unique, Hawaiian native that is often seen in groupings. Slipper Lobsters do not display the oversized antennae often seen as menacing appendages on many lobster. Instead, they possess a slipper or shovel-like structure that is used to dig into mud or sandy substrate. The Regal Slipper Lobster will bury itself or will dig in search of mollusks, snails, or worms to eat. A hardy, but not reef safe invertebrate, its color also makes it an intriguing aquarium inhabitant. Its dark, flattened carapace is outlined in bright red, sometimes varying into purple shades. Growing to about eight inches in length in the wild, it is a true carnivore and should be provided meaty foods. The tails of the Regal Slipper are, as with many other Lobsters, sold and prepared for human consumption. The Regal Slipper Lobster is basically a nocturnal creature, but may be visible through the day on rock overhangs and in the shadows. Eventually, the lobster may learn that food is present more during daytime hours and may break this habit. Typically shy initially, this lobster is a highly effective scavenger that will feed on most any meaty food. It is a true carnivore that has a penchant for clam meat. Medications containing copper must never be used in the presence of Lobsters (or of most hard-shelled crustaceans.) All Lobsters require Live Rock or similar aquarium decoration to use for hiding, especially when molting. This species must molt in order to grow. Molting generally occurs at night, when the lobster will lay on its back and exit its exoskeleton. A new exoskeleton is excreted and will harden over a period of several hours. The animal is vulnerable at this time and should not be disturbed. Proper iodine levels assist with successful molting.
Notes: Lobsters are sensitive to changes in water conditions such as temperature, pH, and salinity. Acclimation should occur over a period of a few hours to ensure best chances for a successful transition.
