Found in shallow rocky reefs, coral reefs, and seagrass beds, they play a crucial role in maintaining ecological balance by grazing on algae, which helps control its growth. Their diverse sizes and colors make them visually appealing, and their rounded bodies with slender spines truly do resemble a sewing pincushion.
In aquariums, these urchins tend to be a bit shy, so providing plenty of rocks and hiding spaces is essential for their well-being. Their charismatic behavior and efficiency in managing algae make them highly desirable among marine aquarists. One potential disadvantage of keeping urchins in an aquarium is their tendency to collect shells and other small, lightweight objects, which can create chaos among your aquarium decorations. It's important to consider this behavior.
These urchins range from an 1-3 inches in diameter but can grow to larger lengths.
