The Derasa Clam, Tridacna derasa, is a beautiful giant clam comprised of warm base colors and illuminating accents. Aquacultured Derasa Clams, like these species, are especially acculturated for the home aquarium and turn out to be exceptionally hardy. Coloration patterns range from blue, black, brown, gold, yellow, and white with accents. Derasa Clams will attach upon introduction to your tank. Therefore it is recommended that once attached that attachment is permanent. If the clam must be removed, though ill advised, it is best to take a razor blade and gently separate the clam's foot from the attachment point. They obtain nutrients through photosynthetic algae but will readily take direct feedings. Derasa Clams are the hardiest giant clam species suited for the home aquarium, and if proper tank conditions are met, they can grow up to 20 inches in captivity.
The coloration was nice and it was larger than I was expecting. Far larger than the Maximas they offer. I placed my in the substrate of my 120 gallon. Its been two months and its been doing great.
Arrived healthy. Looks just like the photo! Happy as a ...clam.
beautiful addition to a tank. with proper acclimation, it easily adapts. it will move itself about the tank until it finds a location it likes. make sure tank mates don't like clams as part of their diet, or you might simply buy a very expensive meal for a crab or fish...
