Why We Like It:

Bell’s Urchin is a compact, hardy grazer ideal for reef tanks needing help with algae control. It’s known for its decorative camouflage behaviour, often covering itself with shells or substrate. While reef safe in feeding habits, its bulldozing nature means it’s best suited to tanks with well-secured corals. A good clean-up crew member for medium to large systems.
