Common name: Stripe-leg spiny lobster

General information

The Blue-Legged Sand Lobster, Panulirus femoristriga, is a striking marine invertebrate known for its vibrant blue legs and antennae. It is a nocturnal creature that spends most of the day hiding in crevices and under rocks. This species is not as common in the aquarium trade as other lobsters, but it can be a fascinating addition to a well-established reef or fish-only tank.

Care

Caring for a Blue-Legged Sand Lobster requires a tank with plenty of hiding places and a sandy substrate to mimic its natural habitat. They are omnivorous and will scavenge for food, but their diet should be supplemented with meaty foods like shrimp, mussel, and fish flesh. It's important to note that they can grow quite large and may become aggressive, so they should not be kept with small fish or invertebrates that could become prey.

Reproduction

In the wild, Panulirus femoristriga engages in a complex mating ritual that involves a courtship dance and the male depositing a spermatophore on the female. In captivity, breeding is rare, but providing an environment that closely mimics their natural habitat can increase the chances of successful reproduction.

Habitat

The Blue-Legged Sand Lobster is found in the Indo-Pacific region, from the eastern coast of Africa to the western Pacific Ocean. They typically inhabit coral reefs and rocky areas, often at depths where light is limited. They are known to burrow in the sand during the day and emerge at night to feed.
