The Crocea Clam, Tridacna crocea, also known as the Crocus Clam and Boring Clam is a vibrantly colorful  clam. It releases acids to penetrate rocks and other substrate using this extraordinary ability to protect itself from harsh water conditions and predators. Their colors vary from purples, blues, browns, golds, oranges, and yellows. 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 water flow. 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.

I ordered two of the .75-1.25 inch when they were on sale for $68. Too hard to pass up. My tank was relatively new and is nothing fancy but I knew my lighting was sufficient for these guys so I decided to go for it. First tridacna clams and first time ordering from an online supplier and I couldn’t be happier. Both were opening up during acclimation and were super responsive when shadows passed over. Well over a month later and both are doing super well with obvious white new growth on their shells and fully open mantles all day every day. I’m very satisfied with these captive bred clams and in general.
