Common name: Spider Conchs

The genus Harpago, commonly known as Spider Conchs, includes some of the most visually striking marine gastropods. These mollusks are characterized by their elongated, spiny shells that resemble spider legs, giving them a unique and exotic appearance. They are primarily found in tropical Indo-Pacific waters, often inhabiting sandy or rubble substrates near coral reefs. Their shells are not only beautiful but also serve as excellent camouflage against predators, blending seamlessly with their surroundings.

Spider Conchs are herbivorous, feeding mainly on algae and detritus. This makes them beneficial additions to saltwater aquariums, as they help control algae growth and contribute to the tank's overall cleanliness. However, they require a well-established aquarium with plenty of live rock and a sandy substrate to mimic their natural habitat. They are generally peaceful and can coexist with a wide variety of tank mates, but care should be taken to ensure they are not housed with aggressive species that may harm them.

One fascinating aspect of Spider Conchs is their ability to "jump" or propel themselves short distances using their muscular foot and operculum. This behavior is not only intriguing to observe but also serves as a defense mechanism in the wild. While they are hardy and adaptable, maintaining stable water parameters is crucial for their health.

For aquarists, Spider Conchs are both functional and decorative, making them a popular choice for reef tanks. Their unique appearance and beneficial algae-eating habits make them a standout addition to any marine aquarium.
