Care

Pronghorn Spiny Lobsters require a well-structured aquarium with plenty of hiding places and room to roam. They are nocturnal and can be quite shy, so providing ample shelter is crucial. They are omnivorous and will accept a variety of meaty foods as well as some plant matter. Caution should be taken as they can prey on small fish and invertebrates.

Reproduction

In the wild, Pronghorn Spiny Lobsters migrate in large groups to spawn. In captivity, breeding is rare and challenging. They release larvae into the water column, which go through several planktonic stages before settling to the bottom as juveniles.

Symbiosis

While not known for a specific symbiotic relationship like clownfish and anemones, Pronghorn Spiny Lobsters do play a role in the reef ecosystem by scavenging and helping to keep the reef clean.

Habitat

Panulirus penicillatus is typically found in coral reefs, rocky areas, and crevices from shallow waters to depths of about 100 meters. They are widespread throughout the Indo-Pacific, from the Red Sea and East Africa to the Central Pacific.
