Maxima Clam (Tridacna maxima) Care
The Maxima Clam, Tridacna maxima, is also known as the Rugose Clam. These clams originally come from the Indo-Pacific region. They can reach up to 16″ in the wild, but typically grow to no more than 8″ in an aquarium. They have very intense mantle colors in various shades of blue. These clams are graded by color intensity, which affects the cost.
Clams are filter feeders and will get most, if not all, of their food from the water column. Small clams may need help to grow and can be given supplements of greenwater or phytoplankton a couple of times a week.
Although clams require strong lighting, they should be slowly acclimated to your tank’s lighting by starting them on the sand and then slowly moving them up higher over a period of a week or two. When introducing them to the tank, you may want to place them on a small rock or disc that can be moved; once a clam attaches to a surface, it should never be pulled off – this will kill your clam.
Maxima clams should be housed in a tank of at least 55 gallons with excellent water quality. Clams are peaceful and will not both fish, corals, and invertebrates. Ensure that you do not introduce animals that will pick at clam mantles.
