Urchins
Sea Urchins are approximately 2"-3" in diameter, with the spines extending possibly twice that distance. Care must be taken to prevent the Urchins from accidentally overturning rocks in the reef tank causing damage to themselves and other reef inhabitants such as live corals. Sea Urchins make great additions to marine aquariums, consuming undesirable algae and detritus within the tank.
