Common name: Spider Squat Lobster

General information

The Squat Lobster, Chirostylus dolichopus, is a fascinating and colorful addition to the marine aquarium. Despite its common name, it is not a true lobster but rather a member of the Galatheoidea superfamily, which is more closely related to hermit crabs. These creatures are known for their elongated, flattened bodies and the striking patterns on their exoskeleton, which can range from vibrant oranges to subtle pinks and purples, often with contrasting white or yellow spots.

Care

Squat Lobsters are generally hardy and can adapt to life in captivity if provided with the right conditions. They require a well-established aquarium with plenty of live rock for hiding and foraging. They are not aggressive but can be territorial with their own kind, so it's best to keep only one per tank unless the aquarium is large enough to provide ample space for each individual. They feed on a variety of foods, including small meaty items and detritus, making them beneficial for tank cleanliness.

Reproduction

In the wild, Squat Lobsters are known to reproduce via a planktonic larval stage, which would be challenging to replicate in the home aquarium. Therefore, breeding these creatures in captivity is not commonly pursued by hobbyists.

Symbiosis

While not known for any specific symbiotic relationships like those seen in clownfish and anemones, Squat Lobsters do contribute to the ecosystem of the tank by scavenging and helping to keep the substrate clean.

Habitat

Chirostylus dolichopus is typically found in deep-water habitats, often associated with cold-water coral reefs or seamounts. They are adept at navigating the complex structures of their environment and can be found at depths that are usually beyond the reach of recreational diving.
