Long spine sea urchin Marine 2-6cm

Long spine sea urchin Marine 2-6cm

Long spine sea urchins are striking additions to established marine aquariums, prized for their distinctive elongated spines and active grazing behavior. At 2-6cm, these specimens are ideal for intermediate to advanced aquarists seeking functional algae control and visual interest. They feed on algae, detritus, and organic matter, helping maintain tank cleanliness while moving deliberately across rockwork and substrate. Hardy and adaptable, they thrive in stable saltwater conditions with adequate hiding spaces and moderate water flow. Their unique appearance and ecological role make them a compelling choice for reef and fish-only setups alike.
