The **Horseshoe Crab** is a remarkable and distinctive invertebrate, reminiscent of prehistoric times, yet not a true crab. These creatures have a flat body with colors ranging from tan to brown and feature a long spine extending from the back. **Horseshoe Crabs** can grow up to 24 inches and require a minimum tank size of 200 gallons. They are peaceful and generally do not disturb other tank inhabitants, but larger ones may topple corals and occasionally target other invertebrates. Juvenile **Horseshoe Crabs** are suitable for reef tanks, but as they mature, relocation might be necessary.

These crabs thrive in tanks with a deep sand bed, where they burrow to find small invertebrates to eat, also helping to oxygenate the sand. As carnivores, **Horseshoe Crabs** primarily scavenge for leftover food, making them excellent members of a tank's cleanup crew. To enhance their diet, you can introduce small pieces of fresh seafood into the tank.
