Care

Ornate Spiny Lobsters require a large tank with plenty of hiding spaces to mimic their natural rocky habitats. They are nocturnal and can be quite shy, so providing ample cover is essential for their well-being. They are omnivorous and will eat a variety of foods, but their diet should be supplemented with meaty foods like fish, shrimp, and mussel.

Reproduction

In the wild, Panulirus ornatus engages in a seasonal migration to spawn. In captivity, breeding is rare and challenging. If conditions are right, females will carry a large number of eggs beneath their tails, which hatch into planktonic larvae.

Symbiosis

While not known for specific symbiotic relationships like those seen in clownfish and anemones, the Ornate Spiny Lobster does play a role in the ecosystem by scavenging and helping to keep the reef clean.

Habitat

Panulirus ornatus is found in tropical and subtropical waters of the Indo-Pacific region. They inhabit coral reefs and rocky outcrops, often hiding in crevices during the day. They can be found at depths ranging from shallow waters to about 100 meters.
