The Blue Tuxedo Sea Urchin is an excellent algae eater and controls the excessive growth of the same in the aquarium. It helps in maintaining the cleanliness in the aquarium by feeding on the algae. The Blue Tuxedo Sea Urchin is best kept in an aquarium with sufficient growth of algae. It is nocturnal and comes out at night in search of its prey, as during day time it mainly rests over their hiding spots. The Blue Tuxedo Sea Urchin features blue or black bands in between red, brown or dark spines. It also acts as a water quality indicator and loses its spines if the water quality is not good. The Blue Tuxedo Sea Urchin exhibits an odd behavior of carrying objects on its back such as coral, rock, or algae, just to keep it covered from bright light. The Blue Tuxedo Sea Urchin belongs to the family named Temnopleuridae and is also known as the Blue Tuxedo Pincushion Urchin, a Blue Stripe Pincushion Urchin, a Blue Sphere Urchin, or a Blue Globe Urchin. It is completely reef safe, passive in nature and hardy in stamina, which makes a great addition to any home aquarium. The Blue Tuxedo Sea Urchin thrives well in rock structures and hence is advised to keep live rocks in the aquarium. There s no distinctive feature that differentiates male from female. It thrives well in temperature range of 72-79 degree Fahrenheit and pH levels of 8.1-8.4.

Urchins belong to a Class known as Echinoidea, which consists of creatures that have a skeleton made of ten plates covered with spines. Urchins have mostly round bodies with protective spines on their upperside and tubular feet and a mouth on the underside. Artistotle once wrote of the five parts of the Urchin's mouth: "In reality the mouth-apparatus of the urchin is continuous from one end to the other, but to outward appearance it is not so, but looks like a horn lantern with the panes of horn left out." This holds true today as the mouth of the Urchin is referred to as "Aristotle's Lantern". The mouth of the Urchin is used to scrape algae from rockwork. The spines of the Urchin are a defense mechanism that are barbed like that of a fish hook and can inflict serious pain to the predator. These spines can either come to a sharp point or can be stubby and blunt.
