Short Spine Urchin

Short Spine Urchins are hardy, reef-safe grazers that bring dynamic movement and natural algae control to your aquarium. These spiny invertebrates thrive in established systems with moderate to strong water flow and plenty of rockwork to explore. Care is straightforward: maintain stable salinity (1.023–1.025), temperature (72–78°F), and pH (8.1–8.3). Feed occasionally with dried seaweed or algae wafers, though they'll naturally forage on microalgae and detritus. Provide hiding spots among rocks and rubble—they're nocturnal grazers and appreciate shelter during the day. Avoid sudden parameter swings and aggressive tank mates; their spines offer protection, but peaceful reef environments suit them best. A living piece of the reef ecosystem, Short Spine Urchins add character while keeping your tank balanced. Perfect for hobbyists seeking a low-maintenance, visually striking addition to their saltwater setup.
