The Maxima Clam is also commonly referred to within the aquarium trade as the Great Clam or Rugosa Clam. In general, Maxima Clams have larger areas of solid color than the other Tridacna clams, with the two halves of the shell being elongated with a lack of symmetry.

It may also attach itself by its byssal filaments, which it can do in a day or two, so its first placement in the aquarium should be considered a permanent home.
