At AquariumSumps.com we carry a wide range of Tridacna Squamosa and Maxima Clams. All clams are "acclimated" and held for at least two weeks to ensure proper health. All clams we ship are guaranteed to be free of pests (such as pyramid snails), be responsive, NOT be gaping, and have smooth unfolded mantles. We know a great deal about clams and how to keep them healthy. Should you be looking for a specific size, color, or pattern, we always do special orders. All Tridacna clams are shipped Expedited Overnight Shipping. You can be sure you're getting a one of a kind clam in great health when you purchase from AquariumSumps.com. Should you have any questions feel free to contact us. Thank You.
We do not ever get Derasa or Crocea clams in stock because we don't believe they should be kept in captivity. Derasa clams grow to a very large size within a short period and no one other than maybe National aquariums will ever be able to keep a Crocea alive for more than a few years. The longest we have seen a Crocea survive in captivity without beginning to lose its color is 3 years.
