About
Diadema antillarum is a keystone species of Caribbean coral reefs known for its exceptionally long, sharp black spines and critical role in controlling algae overgrowth. Following historical mass mortality events, its presence in reef aquariums contributes to conservation awareness and education. Extreme caution is needed when handling due to its needle-sharp spines.
Care Guide
House in a large, mature reef aquarium of at least 200 L. Provide abundant live rock surfaces for grazing. Handle only with thick protective gloves as spines are needle-sharp and can penetrate deeply. Sensitive to copper-based medications. Requires pristine water quality and stable parameters.
