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.

Big Beautiful AND HEALTHY!!!
This guy is pretty sweet. I only see him a few times a week (typicallyin hides in the sand) up scavenging for food but ive had him for almost a month and so far he is doing great.
