In the home aquarium, T. crocea clams need to be provided intense lighting from metal halides or T5HO, and need to be placed up high on the rocky structures. Also take care not to put the clam in direct flow from powerheads. Being in a strong, unidirectional flow can cause the clam to close and remain shut, which would prevent the clam from collecting enough light for the symbiotic algae. If the clam cannot collect enough light, it will starve and die.
Other things to consider when picking out a spot for your clam are coral neighbors and the ability of the clam to move on its own. Clams are protected by a thick calcium carbonate shell. However, they do have a large fleshy mantle that can be irritated. Reef inhabitants are always competing for light and a nearby coral can easily sting a clam. The irritation would cause the clam to remain closed during the day and could stress the clam out tremendously. But sometimes a clam can solve the problem of nasty neighbors on its own. They can move about on sand or rocks by using their foot to push them along. Clams move slowly, but only a few inches may be required in order to find a suitable location.
Clams are fairly easy animals to keep, but are not recommended for the novice aquarist. Research about proper husbandry is a must and specific types of equipment are required. They are beautiful additions to any aquarium and will certainly attract the interest of guests looking at your tank.
