Genus
Common name: Pincushion Urchin
Scientific name: Microcyphus
Microcyphus is a genus of sea urchins commonly known as Pincushion Urchins. They are characterized by their round, globular shape and long, thin spines that can vary in color. These urchins are often appreciated in the reefkeeping hobby for their algae-eating habits, helping to control algae growth in the aquarium. They are generally peaceful and can coexist with a variety of other reef inhabitants. However, care should be taken to ensure they are not housed with aggressive fish that may harm them. They require stable water conditions and plenty of live rock to graze on.
