General Description: The Pincushion Urchin has a body covered in hundreds of short, uniform spines that vary in color from pink, purple, white, beige, and orange. On average, Pincushion urchins grow to a size of 6″. Pincushion urchins are excellent at controlling algae in a reef aquarium. More of a nocturnal animal, the Pincushion urchin will seldomly be active during the day. Pincushion urchins may be seen with pieces of substrate or empty shells on their bodies; this is normal behavior, as the urchin uses these items to aid in camouflage. The Pincushion urchin is safe to handle.
Diet Requirements: Pincushion urchins are voracious herbivores. They consume various algae on the live rock, including hair algae. If insufficient algae is present, we recommend supplementing sheet algae to prevent starvation.
Tank Requirements: An established, minimum aquarium size of 30 gallons is recommended to house a small Pincushion urchin specimen; as it matures, a larger aquarium may be necessary to accomodate its size. Maintaining stable water parameters is a component to the success of keeping this invertebrate; urchins are intolerable of high nitrates and shedding of its spines is a sign of poor water quality. Generous live rock with some crevices will mimic the Pincushion urchin’s natural environment and give it ample places to graze off of. Loose live rock or corals can be accidentially knocked over by the Pincushion urchin as it moves around. Multiple individuals of Pincushion urchin can be kept together, so long as the aquarium can support it. It is imperative to take time acclimating a Pincushion urchin; we suggest via drip acclimation. Recommended water conditions: 76-78° F, dKH 8-12, pH 8.1-8.4, salinity 1.024-1.026.
