Pencil Urchin

Scientific Name: Eucidaris tribuloides

The Pencil Urchin has thick, blunt, pencil-like spines, often covered in coralline algae and tiny growth.

Why We're Obsessed

Pencil urchins look prehistoric, and they're one of the most unusual-looking urchins you can keep.

Care: Not fully reef safe: may eat corals and coralline algae. Best in a FOWLR or with hardy corals only. Feed algae and meaty foods.
