How to Keep Crocea Clams

Crocea clams are beautiful additions to saltwater aquariums. The vibrant colors and exotic features of this giant clam make it an attractive show piece for a fish tank. An average crocea clam grows to 6 inches in length, and some grow as large as 9 inches. The species is native to tropical regions of the Indo-Pacific waters and commonly lives in shallow areas near shore. Proper crocea clam care is important for keeping its colors bright. It's possible to keep crocea clams in a tank for the course of their long life expectancy.

Instructions

    • 1

      Use a saltwater tank that holds 30 gallons or more. Equip the aquarium with a recirculating water pump and set it to make the water current moderate to high for crocea clam care. Maintain average aquarium temperatures of 75 to 84 degrees Fahrenheit.

    • 2

      Light the tank with a high-intensity discharge light such as metal halide at 6 to10 Kelvin degrees. Lighting is the most important element for crocea clams, which use light to make food through photosynthesis. The clams also feed by filtering nitrates, ammonia and phytoplankton out of the water. Normal salt-water aquarium levels of nitrate and ammonia are adequate for keeping crocea clams. Feed the clams phytoplankton if desired, but it is not a nutritional requirement.

    • 3

      Keep crocea clams in the pebbles or sand at the bottom of the tank or on a secure higher spot on a coral. Position the clams away from direct water currents in spots where they are not prone to falling.

      Maintain a calcium level of 400 to 450 ppm, or parts per million. Use a calcium test kit to measure the level and add calcium supplements as needed.
