Blue Lobster, Panulirus versicolor, is an aquarium addition that helps add species diversity to the home aquarium. Also known as the Spiny Lobster, its color varies in shades of blue and indigo. The white bands that cross its carapace segments and its long, characteristically active antennae are characteristics that denote the Blue Lobster. Not recommended for reef aquariums, it will typically not bother other aquarium inhabitants with the possible exception of some invertebrates and smaller bottom-dwelling fish. Blue Lobsters have been kept with more than one to an aquarium, but this is generally not recommended and they should certainly be kept well-fed, if kept in multiples. Because it can grow to sizes around one foot in length, corals and other ornaments may be toppled by its excavating actions. 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.
