Limulus polyphemus | XXXL

Limulus polyphemus, known as the Atlantic Horseshoe Crab, is a living fossil with a lineage dating back hundreds of millions of years. This XXXL specimen is a striking addition to any large marine aquarium, admired for its distinctive, horseshoe-shaped carapace and unique biology.

Care Level: Moderate care is required to maintain optimal water quality and provide appropriate diet and habitat conditions.

Diet: Limulus polyphemus is a scavenger and detritivore, feeding primarily on small molluscs, worms, and organic detritus. In captivity, offer a varied diet including chopped marine invertebrates, sinking pellets, and occasional live or frozen foods.

Compatibility: Generally peaceful and compatible with other non-aggressive invertebrates and fish. Avoid housing with predatory species that may harm the horseshoe crab.

Reef Safety: Yes. Limulus polyphemus is reef safe and does not harm corals or sessile invertebrates.

Tank Requirements: Due to its large size (XXXL), a minimum tank size of 300 litres is recommended to provide ample space for movement and substrate for burrowing behaviour.

Water Parameters: Maintain stable marine conditions with temperature between 20-25°C, salinity 1.023-1.025 SG, pH 8.1-8.4, and moderate water flow.

Placement: Provide a sandy or fine gravel substrate to allow natural burrowing and foraging behaviour. Ensure the tank has hiding spots and open areas for roaming.

Origin: Native to the Atlantic coast of North America.

Limulus polyphemus is a captivating species that adds both educational and aesthetic value to marine aquariums. Its ancient lineage and unique morphology make it a prized specimen for enthusiasts with suitable tank setups.
