Blue Spiny and Slipper Lobsters – Lobsters in the Aquarium – Part 2

Hello, Frank Indiviglio here.  In Part I of this article we discussed general lobster care and took a look at the Dwarf Red or Hawaiian Reef Lobster, Enoplometopus occidentalis.  Today I’ll introduce the Purple or Blue Spiny Lobster, Panulirus versicolor, and the Hawaiian Brown Slipper Lobster, Parribacus antarcticus.

Purple or Blue Spiny Lobster, Panulirus versicolor

Blue Spiny LobsterRelated to the commercially valuable spiny lobsters of the Caribbean and Mediterranean, this white-dabbled, dark blue to purple beauty hails from the Indian Ocean. 

The 2-5 inch individuals commonly sold are quite popular, but it should be borne in mind that they can reach 8 inches in length, and, given their outrageously long antennae, require a large aquarium.  The antennae break easily in crowded conditions, and, while they will regenerate, continually doing so likely saps the lobster’s strength.

While not as aggressive as smaller, heavily-clawed species, Purple Spiny Lobsters will consume other invertebrates and newly-molted tank-mates.  Related species, usually drabber in color, sometimes appear in the trade, but these grow very large and are best left to commercial aquariums.

The Hawaiian Brown Slipper Lobster, Parrabacus antarcticus

Slipper Lobsters are quite unlike other species in appearance, being extremely compressed in body form.  They live up to their alternative name, “Bulldozer Lobsters” and incessantly move substrate about in the wild and the aquarium.  For that reason, care must be taken in setting up their living quarters, as they can easily crush themselves or their tank-mates during their “construction projects”.  Heavy coral and rock should be placed on the aquarium’s floor, not on the substrate, to prevent their digging beneath.

Unfortunately, many of the Slipper Lobsters sold in the pet trade are the young of quite large species, and may reach 16 inches in length and weigh in excess of 10 pounds when mature (a number of these are commercially valuable food animals).  The Hawaiian Brown Slipper Lobster, however, maxes out at 7-8 inches.  It is, however, quite active and should not be crowded.

Hawaiian Slipper Lobsters are more sociable than most lobsters, and often congregate together.  Newly-molted animals, however, may be attacked (please see Part I of this article).  They are also less retiring than others of their kind, and often forage during the day.

Other Slipper Lobsters

Other species sometimes seen in the trade are the Spanish Slipper Lobster (Scyllarides aequinoctialis), (Range: South Carolina to Brazil) and the Vermillion Slipper Lobster, S. delfosi (Range: south Florida through the Caribbean).  Lobster aficionados may also occasionally find S. martensi of Japan and the Philippine’s Ibacus ciliatus.

Being born with a deep interest in animals might seem unfortunate for a native Bronxite , but my family encouraged my interest and the menagerie that sprung from it. Jobs with pet stores and importers had me caring for a fantastic assortment of reptiles and amphibians. After a detour as a lawyer, I was hired as a Bronx Zoo animal keeper and was soon caring for gharials, goliath frogs, king cobras and everything in-between. Research has taken me in pursuit of anacondas, Orinoco crocodiles and other animals in locales ranging from Venezuela’s llanos to Tortuguero’s beaches. Now, after 20+ years with the Bronx Zoo, I am a consultant for several zoos and museums. I have spent time in Japan, and often exchange ideas with zoologists there. I have written books on salamanders, geckos and other “herps”, discussed reptile-keeping on television and presented papers at conferences. A Master’s Degree in biology has led to teaching opportunities. My work puts me in contact with thousands of hobbyists keeping an array of pets. Without fail, I have learned much from them and hope, dear readers, that you will be generous in sharing your thoughts on this blog and web site. For a complete biography of my experience click here.
