Common Names: China or Porcelain Clam.
Colour: Mantle similar to H. hippopus and T. derasa.
Distinguishing Characteristics: Similar to H. hippopus but shell is thinner and smoother when small. Hippopus porcellanus has numerous fringing tentacles around the incurrent aperture (Lucas, 1988). Max. Length: 40 cm (18 in ).
Similar Species: Hippopus hippopus.
Natural Habitat: This species occurs in the same habitat as H. hippopus but, as mentioned earlier, it has a much smaller geographic range.
Aquarium Care: Little is known about the suitability of this species for the aquarium since live specimens are rarely imported (though the shells are commonly imported for ashtrays or other decorative purposes). It should prove to be as hardy as H. hippopus. This species has not received much attention in aquaculture. It is being cultivated now by the MMDC in Palau, so tank raised specimens may soon become available. Hopefully the

aquaculture of this species will also help to restock its small range, since it has been a target of the shell trade in the Philippines, and its numbers are rapidly dwindling (Lucas, 1988).

The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
