Care

Spider Conchs are generally hardy and can adapt to life in a well-maintained aquarium. They are beneficial as they graze on algae and detritus, helping to keep the tank clean. However, they require a sandy substrate to burrow and an ample supply of microalgae to thrive. It's important to ensure that the aquarium is free from predators that might prey on these invertebrates.

Reproduction

In the wild, Lambis lambis engages in a fascinating mating ritual where males use their long siphon to transfer spermatophores to the female. In captivity, breeding Spider Conchs can be challenging, and successful breeding is not commonly reported in home aquariums.

Habitat

Spider Conchs are found in the Indo-Pacific region, from the eastern coast of Africa to the western Pacific. They inhabit reef flats and shallow lagoons, often burying themselves in sand during the day and emerging at night to feed.
