Keeping Clams in a reef tank has become increasingly popular due to their unmatched beauty and rising accessibility via sustainable aquaculture. This captive propagation specifically has also helped make these clams hardier and more suited to life in an aquarium which means more and more hobbyists are finding long-term success keeping the largest clams on the planet! 

Reef Rax Clam Jammer

One of the big challenges when keeping a clam is simply providing them with a secure place to attach their foot to. Luckily for us, the Reef Rax Clam Jammer exists to tackle this very problem.

Many reefers like to position their Tridacna clams on the sandbed for aesthetic purposes and they are normally found on the seafloor in the wild. That being said, these clams prefer to attach to a solid surface with their Bysall Threads through the hole on the bottom of their shell. You do not want your clam wasting energy trying to the perfect spot for it to attach to as it can spend that energy improving its health and growing capabilities.

The Clam Jammer is a pedestal with a deep recessed hole that is specifically designed to cradle your clam or anemone and provide a solid surface for it to attach to. This will decrease the likelihood of your clam wandering around your tank while providing them with the shelter and positioning they need to thrive.

Each of these cradles is made from 100 percent reef-safe resin and comes in three unique colors to match your aquascape. Reefers can choose from a Coraline purple, a dark brown, and a grey depending on the color of rock within their system. The resin also has the appearance of a natural-looking rock texture to prevent any of these cradles from sticking out like a sore thumb. The texture also helps quickly acquire biofilm on the Clam Jammer bringing its appearance even closer to that of your rock work.

The dimensions of these cradles are 6.5” x 4.75” x 1.5” and the inner recess measures 3.75” x 1.75” x .75”. These measurements will be perfect for keeping most small to midsized clams secure as well as most Bubble Tip, Maxi-Mini Carpet, and Flower Anemones. The bottom surface is sanded completely flat which means the Clam Jammer will sit perfectly on the base of your aquarium.

Tridacna Clam Placement Tips

  • Pick a spot with both good light and flow. Clams usually prefer as much light as most SPS corals.
  • Clams have two openings in the center of their mantle. The larger of the two holes is the inhalant siphon and the smaller one is the exhalant siphon. You will want to position the inhalant siphon in the direction of water flow so that moving water flows naturally into your clam.
  • Keep your clam away from any corals or anemones that can sting it. Especially soft and LPS corals which can have pretty severe stings and can cause major harm to your beloved clam.
