The Banded Urchin has a dark green central body with long, sharp spines, sometimes reaching 20 cm in length. The spines have hundreds of alternating light and dark bands. Some spines are strong, thick, and hollow, whereas others are shorter and finer. During the day it often hides in rocky crevices, and in the wild, can be found in large aggregations with other Banded Urchins.

The aquarium should have stable rock work and some shaded areas. During the night, the Banded Urchin comes out to feed. Juveniles generally eat algae, and the adults are carnivores, preying on invertebrates. Smaller fish, such as the Banggai Cardinal, will often seek shelter among its spines during the day, leaving their protection at night to eat.

Use care when handling the Banded Urchin, the spines are venomous; the sting from there spines are similar to a bee sting.

In the aquarium, food can be placed near its spines or even on them. The spines have the ability to transport the food to its mouth.

It will not tolerate copper-based medications and needs low nitrate levels. If it begins to shed its spines, it is a sign of poor water quality.
