Notes: The Tuxedo Urchin, also known as the Sphere Urchin or Globe Urchin will hide among the rock during the day and will emerge at night to graze on the algae present in or near its home. The Tuxedo Urchin generally roams alone, but several of them could be housed in the same aquarium if it is large enough to provide them with adequate food (algae) and shelter. It is sensitive to high levels of copper-based medications and it will not tolerate high nitrate levels. If it starts to lose a number of spines, it is often due to poor water conditions.
If algae levels are particularly low, its diet will need to be supplemented with dried seaweed.
