    Additional Information & Description

    Tridacna derasa have a broad range in the wild and are found in the Indo-Pacific, Central Pacific and South Pacific as well as the Coral Sea. They occupy outer reef habitats on both sandy and hard packed substrates, and can be found either solitary or in small aggregations at depths ranging from 10 to 60 feet. All Derasa Clams entering the aquarium trade are cultured in the Central Pacific and South Pacific Ocean. Although they can be found in a variety of colorations and patterns in the wild, the ones aquacultured for the aquarium trade are primarily gold, brown, orange, and yellow, with vibrant blue or green trim edging that surrounds the mantle.

    T. derasa will arrive unattached to any rock or substrate, and prefer to be placed in the sand or in a recess of a rock, as they do not attach as firmly to the substrate or rockwork like most other members of the genus. In the home aquarium, Derasa Clams require moderate to intense lighting to thrive as they contain the symbiotic algae called zooxanthellae, and receive the majority of their nutrition from the light through photosynthesis. Smaller T. derasa that are 2" or less in size are much more sensitive to very intense lighting as their membrane is much thinner than larger specimens.

    For this reason care should be taken to properly photo-adapt them to the existing reef aquarium lighting in a similar manner to newly introduced stony and soft corals. When adapting a new Derasa Clam to very intense lighting, it is ideal to set them on a small rock or in a plastic dish with coarse substrate at the bottom of the aquarium. Over time, the clam can then be slowly moved up higher in the aquarium. When maintained in the proper environment, smaller Derasa Clams can double or triple their size in less than a year.

    Tridacna clams are also filter feeders and constantly filter the water for small particulates. Derasa Clams larger than 2" do not require supplemental feedings, but smaller T. derasa that are less than 2" should be fed a phytoplankton or greenwater supplement several times per week if maintained in a nutrient poor reef aquarium.

    Looking for the best food to feed your Tridacna Clams? We recommend AlgaGen Acartia tonsa, AlgaGen Pseudodiaptomus pelagicus, AlgaGen Parvocalanus crassirostris, AlgaGen Tangerine Pod, AlgaGen Moina salina, AlgaGen PhycoPure all info from liveaquaria.com
