Common name: Hairy Squat Lobster

General Information

The Hairy Squat Lobster (Lauriea siagiani) is a fascinating and diminutive crustacean that has captured the attention of marine enthusiasts and underwater photographers alike. Known for its vibrant pink coloration and long, hair-like setae covering its body, this species is a true gem of the reef. Despite its name, it is not a true lobster. Its small size and intricate patterns make it a sought-after subject for macro photography.

This species was first described in 1994 and is named after Wilhelm Siagian who collected the type specimen. It is often found living on barrel sponges (Xestospongia testudinaria), where its coloration provides excellent camouflage. The Hairy Squat Lobster is a prime example of how marine life evolves to blend seamlessly with its environment.

Care

Caring for the Hairy Squat Lobster in a home aquarium can be challenging due to its specific habitat requirements and small size. It thrives in well-established reef tanks with stable water parameters and plenty of live rock. Providing barrel sponges or similar structures is crucial for replicating its natural habitat. These lobsters are nocturnal and prefer dimly lit environments, so subdued lighting or shaded areas in the tank are ideal.

Due to their delicate nature, they are best suited for advanced aquarists who can maintain pristine water quality and provide a peaceful environment free from aggressive tank mates.

Diet and Feeding

The Hairy Squat Lobster is an opportunistic feeder, consuming detritus, plankton, and small organic particles in the wild. In captivity, they can be fed finely chopped seafood, frozen plankton, and high-quality marine pellets. Spot feeding near their hiding spots ensures they receive adequate nutrition.

Feeding should be done sparingly, as overfeeding can lead to water quality issues. Observing their feeding behavior can help determine the appropriate amount and frequency.

Behavior and Compatibility

Hairy Squat Lobsters are peaceful and reclusive creatures, spending most of their time hiding within the folds of barrel sponges or crevices in live rock. They are non-aggressive and can coexist with other peaceful reef inhabitants. However, care should be taken to avoid housing them with large or predatory species that may view them as a snack.

Their small size and cryptic behavior make them a joy to observe for patient aquarists. They are best kept singly or in pairs, as overcrowding can lead to stress.

Symbiosis

The Hairy Squat Lobster has a fascinating symbiotic relationship with barrel sponges (Xestospongia testudinaria). The lobster benefits from the sponge's protection and camouflage, while the sponge remains unharmed. This relationship highlights the intricate interdependence of reef ecosystems.

In captivity, replicating this relationship by providing barrel sponges or similar structures can enhance the lobster's well-being and allow aquarists to observe its natural behaviors.

Health and Common Issues

Hairy Squat Lobsters are relatively hardy if provided with optimal conditions. However, their small size and specific habitat needs make them susceptible to stress and predation. Maintaining stable water parameters and avoiding aggressive tank mates are essential for their health.

When selecting a Hairy Squat Lobster, look for individuals with intact appendages and vibrant coloration. Avoid specimens that appear lethargic or have damaged setae.

Habitat

The Hairy Squat Lobster is native to the Indo-Pacific region, particularly around Indonesia and the Philippines. It inhabits coral reefs and is most commonly found on barrel sponges at depths ranging from 10 to 30 meters. These sponges provide both shelter and camouflage, making them an essential part of the lobster's habitat.

Replicating this environment in captivity involves providing plenty of live rock and sponge-like structures, along with stable water conditions and moderate flow.
