The ORA® Aquacultured Hippopus Clam is also known as Horse's Hoof, Bear Paw or Strawberry Clam. The shell of this clam is very thick with prominent ribs, and has reddish blotches making it easy to differentiate from other clams. The mantle of these clams does not extend past the edge of the shell and are golden in color with stripes and purple or green dots. The large opening in the mantle, which is called the incurrent aperture, lacks the tentacles that are common with other clams within the Tridacnidae family. These are relatively fast-growing clams that process a lot of water for their size which helps in controlling nutrients in a reef aquarium.
A well-established reef aquarium with moderately high lighting is ideal for the ORA® Aquacultured Hippopus Clam. They prefer to be seated in the substrate with a low to moderate water current. As they grow, the ORA® Aquacultured Hippopus Clams will eventually lose their byssal gland and will rely on their weight to keep them in place. It is ideal to place these clams on a flat rock that is buried in the substrate to keep access to the byssal opening away from any potential predators.
The ORA® Aquacultured Hippopus Clam requires calcium levels of at least 280 mg/L, preferably 380-440 mg/L, as well as adequate strontium and iodine. They require moderately high lighting from which they receive part of their required nutrition. They also need nutrients within the water in which they can feed. Provide phytoplankton in the form of a filter feeding food, weekly. They also feed upon ammonia and nitrates within the aquarium and are a good addition to the reef aquarium for helping control these nutrients.
