The Crocea Clam, Tridacna crocea, also known as the Crocus Clam and Boring Clam is a vibrantly colorful boring clam. It is boring in the sense that is releases acids to penetrate rocks and other substrate, not that is is uninteresting. It uses this extraordinary ability to protect itself from harsh water conditions and predators. Their colorations vary from purples, blues, browns, golds, oranges, and yellows. They are quite spectacular specimens and will certainly brighten up your tank. Crocea Clams often live in large colonies in the wild and will group together if there are multiple in a tank. They will attach rather quickly upon introduction into a tank so be sure of the attachment point because it may be permanent. If the clam must be removed, though it is advised against, use a razor blade to cut as close to the connection of the foot and rock as possible. Crocea Clams require high levels of light to thrive as well as good waterflow. They get nutrients from photosynthetic algae paired with the Crocea Clam. The Crocea Clam is a hardy species and will thrive under these proper conditions.
