Description
Overview: The Horse Hoof Clam is a unique and robust species of giant clam, named for its distinctive rounded, heavy shell that resembles a horse’s hoof. Known for its earthy tones and beautifully patterned mantle, this clam brings a natural, exotic touch to large reef aquariums.
Origin: Native to the Indo-Pacific region, particularly around the Philippines, Indonesia, and northern Australia, Hippopus hippopus inhabits sandy reef flats and lagoons, often partially buried in substrate.
Feeding: Primarily photosynthetic, this clam hosts symbiotic zooxanthellae and thrives under strong reef lighting. Supplement with phytoplankton and microplankton, especially in younger clams or systems with lower nutrient availability.
Tank Mates: Peaceful and reef-safe, the Horse Hoof Clam is best kept with non-aggressive fish and invertebrates. Avoid housing with species that may nip at its mantle, such as angelfish or some wrasses.
Water Parameters:
Temperature: 76–82°F (24–28°C)
pH: 8.1–8.4
Salinity: 1.023–1.025 SG
Calcium: 400–450 ppm
Alkalinity: 8–12 dKH
Lighting: High-intensity reef lighting (LED or metal halide)
Note: Due to its size and substrate-burrowing behavior, the Horse Hoof Clam is best suited for large, mature reef tanks with stable water chemistry and ample space on the sand bed.
