The Purple Lobster is a nocturnal species and mainly comes out at night in search of foods. It needs lots of hiding places, thus keeping live rocks and caves are necessary in an aquarium. The Purple Lobster can not get along well with other inhabitants and may injure them, due to its aggressive and territorial behavior. It is advised to be kept only one per tank to avoid any unnecessary aggressive behavior in the tank. The Purple Lobster is considered a scavenger that likes to sift through the sand for detritus and thus helps in keeping the aquarium aerated. It feeds on small fish, therefore fishes should be kept selectively according to its size. It is sensitive to copper based medications and extreme nitrate levels. Poor water conditions should be avoided in the tank containing the Purple Lobster. It thrives well in a temperature range of 72-78 degrees Fahrenheit, pH of 8.1-8.4 and with high water quality. The Purple Lobster is easy to care for. The aquarium should be added with a thick sand and gravel bed for burrowing, also with lots of rocks for hiding places. The Purple Lobster undergoes molting and needs traces of iodine to ensure proper molting. It is completely snail safe, unlike crabs, and do not disturb or harm snails. The Purple Lobster is reef safe if it is fed properly and gets plenty of hiding place in the tank.
