Common name: Money Cowrie

General Information

The Money Cowrie, scientifically known as Monetaria moneta, is a small marine gastropod mollusk that has been historically significant due to its use as currency in various cultures. Its smooth, glossy shell is distinctively shaped like an oval, with a flattened base and a domed top, making it easily recognizable among shell collectors and marine enthusiasts.

Though not a common addition to home aquariums, the Money Cowrie is appreciated for its unique appearance and historical significance. Its role in trade and as a symbol of wealth in ancient cultures adds an intriguing historical and cultural dimension to its allure.

Care

While not typically kept in home aquariums, those who wish to include the Money Cowrie in a marine setup should ensure a stable environment with plenty of live rock and sandy substrate. These snails are generally hardy but require a well-maintained tank to thrive. They are best suited to tanks that mimic their natural reef habitat, with stable water parameters and moderate flow.

Diet and Feeding

Money Cowries are herbivores, primarily grazing on algae and biofilm that accumulate on rocks and other surfaces. In captivity, they can be fed a diet of algae wafers and blanched vegetables to supplement their natural grazing habits. Providing a variety of plant-based foods will ensure they receive adequate nutrition.

Behavior and Compatibility

Money Cowries are peaceful and non-aggressive, making them suitable for community tanks with other non-predatory species. They spend much of their time grazing on algae and are generally nocturnal, becoming more active at night.

Due to their peaceful nature, they can be kept with a variety of other reef-safe species. However, care should be taken to avoid housing them with aggressive fish or invertebrates that may prey on them.

Health and Common Issues

Money Cowries are generally hardy but can be sensitive to poor water conditions. Regular tank maintenance, including water changes and monitoring of water parameters, is essential to prevent issues such as shell erosion or other stress-related conditions.

Habitat

Money Cowries are found in tropical and subtropical regions of the Indo-Pacific, often inhabiting coral reefs and rocky shorelines. They prefer shallow waters where they can easily access their primary food source, algae.
