ORA® Aquacultured Ultra Grade Colored Maxima Clams are premium specimens specifically selected and graded for their exceptional coloration and patterning. Demonstrating vibrant color combinations of varying shades of blues and purples artistically accentuated by highly-ornate patterning, the ORA Ultra Grade Colored Maxima Clam is a visual feast sure to inject spectacular visual interest to your reef aquarium, especially when properly illuminated.

Tridacna maxima clams have the widest distribution of any Tridacnid species. They can be found from the Red Sea, throughout the Indo-Pacific region, to Australia and Polynesia. In the wild, Maxima clams usually occur in areas with clear shallow water and high currents where they are known to form high-density populations reaching a maximum size of 12". Maxima clams can be identified by their elongated shell that lacks symmetry and narrowly spaced scutes or scallops on the upper portions of each side of their hinged shells. Like some other members of its genus, Maxima clams attach to hard substrate or rockwork with thread-like structures called byssal filaments and can eventually burrow or bore into porous substrate over time.

Smaller ORA Maxima clams tend to be more sensitive to very intense lighting as their membrane is much thinner than larger specimens. For this reason, care should be taken to properly photo-adapt them to your reef aquarium lighting in a similar manner when introducing new stony and soft corals. When photo-adapting a new Maxima clam to very intense lighting, it is ideal to set them on a small rock or in a plastic dish with coarse substrate placed at the bottom of the aquarium. Over time, the clam can then be slowly moved up higher in the aquarium.

The ORA Ultra Grade Colored Maxima Clam relies heavily on the photosynthetic zooxanthellae cells growing in its mantle to satisfy the majority of its nutritional needs. However, all clams also require micro foods designed for filter feeders, especially when small. Offer phytoplankton and other micro foods.
