Which of these organisms is explicitly listed as an appropriate meaty component for the captive diet of *C. daedalma*?
Answer
Black worms (Lumbriculus variegatus)
The captive diet for *Chaetodon daedalma* must be varied, combining vegetable matter with appropriate meaty and invertebrate selections to address their wild consumption habits. The text explicitly lists several recommended meaty items intended to complement the greens. These include live or frozen mysis shrimp, live or frozen brine shrimp, krill or zooplankton, and importantly, Black worms, scientifically known as *Lumbriculus variegatus*. These items satisfy the invertebrate portion of their broad, opportunistic palate.
