Notes
Largest commonly-kept Tridacna species, adult specimens reach 18+ inches. Hardiest of the trade clams, tolerating moderate light better than Maxima or Squamosa. Earthy green, gold, or blue mantle morphs (less iridescent than Maxima). Place on the sand bed, not on rock.

Every coral below passes the reef-compatibility engine when placed alongside Derasa Clam. Verdicts account for stinging sweepers, wandering anemones, and overgrowth pressure. Cautions mean you can still keep both but should plan placement (frag plugs, separate rockwork, sight breaks).
