Habit & Habitat:

  • In its natural habitat, Crocea Clam is found in groups.
  • When Tridacna crocea perceives any danger, it tries to burrow itself in Calcareous substrates. To penetrate such substrates, Crocea Clam secretes an acidic substance which dissolves the Calcium Carbonate present in the substrates. The dissolution is accompanied by the penetration of Tridacna crocea in the substrate. To penetrate, the Byssal Muscles help facilitate the vigorous clap of the thick shell of Crocea Clam. Due to this clapping, the ridges of the shell dig into the dissolved Calcareous substrate and Tridacna crocea burrows in there to protect itself from its predators such as, Starfish and Butterfly Fish to name some.
  • The mantle of Crocea Clam is patterned with a mixture of fluorescent colors.
  • Tridacna crocea has a thick shell, at the posterior end of which are fine ridges resembling a file. The anterior end of the shell has thin scales.
  • The pipe, called Siphon, receiving water incurrent contains tentacles.

  • Supplements: Add Iodine, Strontium, Trace Elements and Calcium to the tank water as the dietary supplements for the Tridacna crocea therein. Maintain the Calcium level between four hundred milligrams and four hundred and eighty milligrams per liter of the aquarium water.
  • Tridacna crocea is moderately difficult to maintain.
  • Shrimps, Angelfish, Butterfly Fish, Starfish and crabs may attack Crocea Clam.
  • Fluctuations in the pH of your marine aquarium may give pH shock to the Tridacna crocea therein.
  • The color brightness, the growth and the life of Crocea Clam is directly proportional to the intensity of light the clam is exposed to. Therefore, be very particular that ample light reaches to the Tridacna crocea placed in your marine aquarium.
