Pincushion Urchin Species Information

The Lytechinus variegatus urchin comes from the Western Atlantic Ocean and prefers seagrass meadows and other soft-bottom habitats. Totally reef-safe and fond of consuming unsightly hair algae, it has long been a favorite sea urchin among marine aquarium enthusiasts. It is also important to note that these hardy individuals represent some of the first captive-raised specimens to become available to hobbyists. In addition to being a sustainable alternative to wild caught urchins, they also make a great addition to any clean up crew that will help control and eliminate nuisance algae.

Ocean, Reefs, and Aquariums™ (ORA™) is a world leader in marine aquaculture. In addition to captive bred fish, they also produce many species of captive bred marine invertebrates.
