Maxima Clam (Tridacna maxima) saltwater invertebrate

Maxima Clams are intensely colored photosynthetic clams that require a mature, stable reef and typically stronger light than Derasa clams. Place a Maxima on secure rock or a clam cradle where its byssal opening is protected and it can attach naturally. Maintain stable salinity, alkalinity, calcium, and magnesium, use indirect flow, and allow clear space for full mantle extension.

Strong, appropriate lighting supplies much of the energy for a healthy Maxima. Very small specimens may benefit from fine suspended foods, but overfeeding can degrade water quality. Use measured nutrient management and stable chemistry.

Strong Reef Lighting Dissolved Nutrients Fine Phytoplankton
Peaceful and stationary after attachment. Do not cut or pull byssal threads. Inspect for pyramidellid snails, pinched mantle, bleaching, and fish that nip the mantle.

  • Where should I place a Maxima Clam?
    Place it on stable rock or a purpose-made cradle under suitable reef lighting.

    Usually yes. Confirm actual intensity with a PAR meter and acclimate the clam gradually.
  • Can I move it after it attaches?
    Avoid moving an attached clam unless necessary and never pull or cut tissue blindly.
