Common name: Torri's Chiton
General Information
The Torri's Chiton, scientifically known as Rhyssoplax torriana, is a fascinating marine mollusk belonging to the class Polyplacophora. This species is characterized by its segmented, armor-like plates that provide protection while allowing flexibility. Found in intertidal zones and rocky shores, this chiton is a hardy and intriguing addition to marine aquariums, particularly for enthusiasts interested in unique invertebrates.
Chitons like Rhyssoplax torriana play an essential role in the ecosystem as grazers, helping to control algae growth on rocks and other surfaces. Their ability to cling tightly to substrates makes them well-suited for environments with strong currents, and they are often admired for their resilience and understated beauty.

Care
Caring for Torri's Chiton is relatively straightforward, making it a suitable choice for aquarists with some experience in maintaining marine invertebrates. They thrive in aquariums with ample live rock, which provides both a grazing surface and shelter.
These chitons are nocturnal and prefer dimly lit environments, so aquarists should consider providing shaded areas or caves within the tank. Avoid placing them in tanks with aggressive fish or invertebrates that may harm them.
Diet and Feeding
Torri's Chiton is an herbivore, primarily feeding on algae. In captivity, they will graze on naturally occurring algae on rocks and glass. If algae levels are insufficient, supplemental feeding with algae wafers or sheets can be provided. Ensuring a steady supply of algae is key to their health and well-being.
Behavior and Compatibility
Torri's Chiton is a peaceful and solitary species, making it an excellent addition to community tanks with other non-aggressive inhabitants. They are slow-moving and spend most of their time grazing on surfaces. Their armored plates provide some protection, but care should still be taken to avoid housing them with predatory species.
Health and Common Issues
Chitons are generally hardy but can be vulnerable to poor water quality and sudden parameter changes. Regular monitoring of water conditions and maintaining a clean, stable environment will help prevent stress and disease. When introducing a chiton to your tank, ensure that it is acclimated slowly to minimize shock.
Habitat
Rhyssoplax torriana is native to the rocky intertidal zones of the Indo-Pacific region. These environments are characterized by strong currents, abundant algae, and fluctuating tidal conditions. Replicating these conditions in captivity, including moderate water flow and plenty of grazing surfaces, will help ensure their success in an aquarium setting.
