Genus
Common name: Long-spined Sea Urchin
Scientific name: Stylocidaris
Stylocidaris is a genus of sea urchins known for their distinctive long spines. They are a popular choice for reef aquariums due to their algae-eating habits, which help control algae growth. These urchins are generally peaceful and can coexist with a variety of tank mates. They require stable water conditions and plenty of live rock to graze on. It's important to handle them with care as their spines are sharp and can break off easily.
