Here are a couple of pics of my Crocea clams, the one on the left I just bought about a month ago. The clam on the right has been with me for over 2years.  Both are extremely colorful although the picture on the right doesn’t do the clam justice. 

  Crocea clams are fairly delicate and is probably the hardest of the tridacna clams to keep.  They prefer moderate to high water movement and intense lighting. They are found in the indo-pacific in shallow areas near shore.  They burrow themselves into the substrate or live rock.  This species of tridacna can reach lengths up to nine inches.  They can be any combination of purple, yellow, blue, green, brown or gold color.

  These are excellent additions to the reef aquarium that can provide an excellent color addition to any tank.  These clams should only be tried by advanced reef keepers.
