Horseshoe Crab ==Limulus polyphemus== The Saltwater Horseshoe Crab is a bottom feeding scavenger. They like a deep, fine sandbed with a lot of open space to roam around in. They do get large over time- females can reach sizes of about 12 inches. Saltwater Horseshoe Crabs will dig through the sand in search of worms or other small creatures to eat. In the aquarium their diet may need to be supplemented with pieces of shrimp or squid as there might not be enough food in the aquarium otherwise. | |= COMMON NAME: ||= Horseshoe Crab | |= SCIENTIFIC NAME: ||= Limulus polyphemus | |= SIZE AVAILABLE: ||= ~3 inch | |= MINIMUM TANK SIZE: ||= 1 per 100 gallons | |= FOOD/DIET: ||= Omnivore | |= CARE LEVEL: ||= Moderately easy | |= REEF SAFE: ||= Yes | |= AVAILABILITY: ||= Most always available - 99% | *Needs a large deep fine sand bed to thrive. *One per 100 gallons is recommended.
