Horseshoe crabs are very efficient scavengers and are great for aerating and maintaining sand beds. They dig through sand and gravel in search of worms and any organic debris. It will move the substrate around almost nonstop in its search for food. They are reef safe, but when they grow to a large size they can be harmful to fish and invertebrates, especially worms and clams. Although it may find some food scavenging, its diet should be supplemented with meaty items such as pieces of squid and shrimp.
