Longspine Urchin

The black longspine urchin is a beautiful reef safe urchin that is a great addition to a good sized tank. It is predominantly black in color with some blue markings and a reddish eye in the center of their body. 

This urchin is venomous (equivalent to a bad bee sting), so be cautious when adding to your tank. It will use it’s long spines to fend off large predators, so it is a great addition for algae control in a predator tank. They are nocturnal so they will roam the tank at night eating algae.
