The Halloween Urchin is a unique and hardworking reef invertebrate known for its striking colors, fascinating appearance, and excellent algae-eating abilities. With its bold orange, black, and white markings, this urchin adds both personality and function to a saltwater aquarium.
These active grazers spend their time roaming across rockwork and aquarium surfaces, consuming nuisance algae and helping keep your reef clean. Halloween Urchins are especially appreciated by reef keepers looking for a natural solution to algae control.
Like other urchins, they use their tube feet and specialized mouthparts to scrape algae from hard surfaces. They may also pick up small loose items, shells, or pieces of rock and carry them on their spines as camouflage.
