You can get blue croceas and blue maxima clams all day long but for some reason blue is the holy grail coloration of Tridacna maxima and Tridacna derasa clams. Blue Maxima clams are show-stopping dramatic looking clams but blue Derasa clams are much more rare in the American reef aquarium scene.
Very soon visitors to Jay’s Aquatics in Salem, New Hampshire will be graced by the sheer presence of a nice big, 10″ blue Derasa clam. But this is no ordinary fresh wild Tridacna derasa clam, this one has been baking under artificial aquarium light and conditioning in the show tanks of Oculus Aquatics for over a year and half. Lucky clam!
