Are you thinking of adding an intriguing marine creature to your saltwater tank? The Arrow Crab is a perfect choice! Known also as the Spider Crab, it’s a fascinating creature. Its unique arrow-shaped body and long legs make it a stand-out.
The Arrow Crab can grow up to six inches and fits well in reef environments. They like hiding in small caves or cracks in the reef. They are tough and live long but watch out, they might eat smaller fish and crustaceans. So, choosing the right tankmates is key.
The Arrow Crab is not picky about food. It looks around corals and mushrooms for snacks and likes meaty, flake, and tablet foods too. It loves eating Bristle Worms, helping to keep their numbers down in your tank.
Before getting an Arrow Crab, think about how big it can get and its need for hunting. Your tank should fit its needs, and you should pick tankmates that can live with it without trouble. With careful planning, an Arrow Crab will add wonder and beauty to your tank.
Arrow Crab Description and Natural Habitat
The Arrow Crab stands out because of its long legs and unique head shape. This crab can become quite large, reaching a leg span of up to 8 inches. Usually, females are smaller than the males.
This crab makes its home in the western Atlantic, especially in shallow coral reefs. They hide in Lebrunia anemones by day and hunt at night. They eat feather duster worms and tiny reef animals. Using a flashlight, you can find them hiding under rocks and in crevices.
For those keeping Arrow Crabs, a tank size of 30 gallons or more is best. This gives them plenty of room.
Arrow Crab Compatibility
The Arrow Crab can be a bit tough to keep with other sea life. Though usually reef safe, it might hunt if it’s really hungry. It could go after coral polyps or even small live fish. So, it’s key to pick tankmates that can dodge its pincers. Small, friendly crustaceans like shrimp shouldn’t be kept with the Arrow Crab. Bigger, faster fish are better friends for it. Having lots of hiding spots in the tank is also essential. This helps the Crab find a safe spot to chill.
The blue tang is a great buddy for the Arrow Crab. With its speedy swim and big size, the blue tang usually stays off the Crab’s menu. Quick and nimble fish like clownfish and wrasse also get along well with the Crab. They’re good at steering clear of its pincers. Big guys like the lionfish and triggerfish can hang with the Arrow Crab too. They add some excitement to the tank as well.

Making sure the Arrow Crab has plenty of places to hide is super important. Natural live rock spots and fake caves work great for hiding. These hiding places lower the Crab’s stress and make everyone get along better.
Thinking about everyone’s needs helps make a peaceful saltwater tank. Choose the right fish friends and give the Arrow Crab spots to hide. This way, you can have a happy tank where the Arrow Crab and its tankmates flourish together.
Feeding Arrow Crab
Feeding Arrow Crabs is quite easy because they eat almost anything. They are not picky and will eat both live and dead food in their tank. This behavior makes it easy for aquarium owners to feed them.
Arrow Crabs love eating bristle worms. Bristle worms are a good snack for them. This love for bristle worms can help control bristle worm numbers in your aquarium.
“The Arrow Crab’s natural predation on bristle worms is not only practical but also beneficial for maintaining a healthy ecosystem within your aquarium.”
To help Arrow Crabs grow, you can give them sinking foods like invertebrate tablets. These foods have the right nutrients for them. It’s important to choose foods made especially for invertebrates.
Arrow Crabs also help clean the tank by eating leftovers. They will eat food that falls to the tank’s bottom. But, make sure they get enough food to keep them from going after other tank mates. Regular feeding and watching how much they eat are key.
