Common name: Mollusks

Mollusca is a diverse phylum in the animal kingdom, encompassing a range of organisms known for their soft bodies and, in many cases, external calcium carbonate shells. This group includes snails, bivalves, octopuses, and squids. Many mollusks are beneficial in reef aquariums, particularly snails and bivalves, which can act as algae grazers, substrate cleaners, and biological filters. Octopuses, while fascinating, require specialized care and are not recommended for most hobbyists due to their intelligence, escape tendencies, and potential to prey on other tank inhabitants.
