About this item

Black Longspine Sea Urchin

Black Longspine Sea Urchins (Diadema setosum) are highly effective algae-grazing invertebrates known for their long, slender spines and constant movement across rockwork and substrate. Their active grazing behavior helps control nuisance algae, making them a powerful addition to reef aquariums struggling with algae buildup.

These urchins continuously roam the aquarium, consuming film algae, hair algae, and organic buildup while helping maintain cleaner surfaces throughout the system. Their bold appearance and active presence also add dynamic movement to the tank, making them both a functional and visually striking member of a cleanup crew.
