Diadema savignyi | M

Diadema savignyi is a visually impressive sea urchin species prized in the marine aquarium hobby for its long, thin spines and algae-grazing capabilities. This medium-sized urchin can be a valuable addition to reef tanks, helping to maintain algae control while generally being reef safe.

Care Level: Moderate care is recommended due to its sensitivity to water quality and handling. Ensure stable parameters and avoid sudden changes.

Diet: Primarily herbivorous, feeding on algae and biofilm. Supplement with dried seaweed or algae wafers if natural algae growth is insufficient.

Compatibility & Reef Safety: Diadema savignyi is considered reef safe and compatible with most reef inhabitants. However, care should be taken to prevent damage to delicate corals from its spines.

Tank Requirements: A minimum tank size of 75 litres is advised to provide adequate space and water stability. Moderate to strong water flow is preferred to mimic natural conditions.

Placement: Position in areas with ample live rock and algae growth. Avoid high-traffic zones to reduce stress and accidental injury.

Handling: Handle with extreme care or avoid handling altogether due to sharp spines that can cause injury.

With proper care, Diadema savignyi can thrive and contribute to a balanced, healthy marine aquarium environment.
