Echinometra mathaei

Echinometra mathaei – Algae-eating Boring Urchin

Echinometra mathaei, commonly known as the boring urchin or black diadem urchin, is a useful and discreet echinoderm for reef aquariums. This specimen is distinguished by its dark shell and short spines. It is known for its constant grazing activity and its ability to lodge itself in rocky crevices.

An efficient and versatile algae eater

Primarily an algae eater, it actively participates in cleaning the decor by feeding on encrusting algae, microalgae, and biofilm. It can also occasionally consume small pieces of mussel or fish flesh, making it an opportunistic omnivore.

Respectful of the reef decor

Contrary to its name, Echinometra mathaei is not destructive. It does not move decor elements and respects well-fixed invertebrates. It lodges in natural cavities and performs localized grazing without disturbing the aquarium's balance.

To monitor in case of algae shortage

If the tank does not produce enough natural food, it is essential to provide fresh algae such as nori or spirulina. A lack of plant intake can affect its health in the long term.
