Diadema antillarum, commonly known as the long-spined sea urchin, is a visually impressive invertebrate prized for its algae grazing capabilities in marine aquariums. This extra large specimen offers a dramatic addition to mature reef systems, helping to maintain algae control naturally.
Care Level: Moderate care is recommended due to their sensitivity to water quality and handling. They require stable, well-established aquariums.
Diet: Primarily herbivorous, feeding on various types of algae. Supplement with dried seaweed or specialised urchin foods if natural algae is insufficient.
Compatibility and Reef Safety: Generally reef safe but with caution; their long spines can inadvertently damage delicate corals or invertebrates. Avoid housing with aggressive fish or predators such as triggerfish or puffers.
Tank Requirements: A minimum tank size of 100 litres is advised to provide adequate space and stable water parameters. Moderate water flow and lighting conditions that support algae growth are ideal.
Placement: Position on live rock or substrate where it can graze freely without risk of falling or being harassed by tank mates.
Ensure excellent water quality with stable parameters to prevent stress and disease. Regular monitoring and gentle acclimation are essential for successful husbandry.
