Longspine Urchin

Longspine Urchin is the striking addition your marine aquarium has been waiting for. With its long, elegant spines and natural grazing habits, this algae-eating marvel brings both beauty and function to your reef or fish-only tank. Each specimen is unique, with size and spine length varying to create a dynamic, ever-changing focal point in your underwater landscape.

• Efficient algae control—a diligent grazer that helps manage nuisance film and turf algae, supporting a cleaner, healthier display for your corals and invertebrates.
• Visual impact—dramatic silhouette and radiant color contrast add depth and movement to rockwork and sandy bottoms, enhancing the overall aquascape.
• Reef-friendly in mature systems—generally compatible with many peaceful inhabitants in established, well-maintained marine aquariums. Monitor for individual variations and always acclimate slowly.
• Low-maintenance personality—adapts to a stable marine environment. Best results come in tanks with stable salinity, temperature, and pH, and with ample grazing surfaces.
• Careful placement—prefers open spaces to roam and graze, but will explore crevices and rockwork. Provide ample hiding spots and ample circulation to encourage healthy activity.

Bring home a Longspine Urchin to elevate your reef display with its natural artistry and practical algae control. This hardy, eye-catching creature thrives in properly conditioned systems and rewards observers with a dynamic, ever-changing presence that resonates with the beauty of the sea.
