Eucidaris tribuloides

Eucidaris tribuloides – Omnivorous Pencil Urchin for Reef Aquarium

Eucidaris tribuloides, also known as the Antillean lance urchin or pencil urchin, is a fascinating invertebrate with a prehistoric look, typical of Caribbean reefs. It is recognized by its straight, thick, and robust spines, which give it the nickname of pencil urchin.

A Robust and Useful Omnivore

This specimen is a versatile omnivore: it primarily feeds on algae but also enjoys meaty additions such as pieces of mussel or fish meat. This varied diet makes it an effective detritivore, perfect for maintaining the natural balance in a reef tank.

Suitable for both reef and fish-only aquariums, Eucidaris tribuloides is renowned for its robustness and longevity. It is generally harmless to corals but can move small fragments or decorative elements while moving, due to its strength and morphology.
